How can two plants that have different genotypes for a particular inherited characteristics be identical in phenotype?

How can two plants with different genotypes for a particular inherited characteristic be identical in phenotype? One could be homozygous for the dominant allele, while the other is heterozygous.

Bạn đang xem: How can two plants that have different genotypes for a particular inherited characteristics be identical in phenotype?

Is it possible to have different genotypes but the same phenotype?

Since the phenotype is the result of an interaction between genes and the environment, different environments can lead to different traits in individuals with a particular genotype. In addition, different genotypes can lead to the same phenotype. This happens because genes have different alleles.

How can two pea plants be identical in phenotype but have different genotypes for seed color?

How can two pea plants that have different genotypes for seed color be identical in phenotype? One of the two plants could be homozygous for the dominant allele while the other could be heterozygous.

Is the relationship between genotype and phenotype The same for different kinds of traits?

The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.

How does a homozygous round seed plant differ from a heterozygous round seed plant in the F2 generation?

How does a homozygous round seed plant differ from a heterozygous round seed plant in the F2 generation? The round seed heterozygote has a genotype with two different alleles (Rr) while the round seed homozygote has the same allele (RR).

How is it possible that individuals with two different genotypes can have the same phenotype?

Recessive alleles only demonstrate their effect if the individual has two copies of the alleles. Hence, due to the presence of dominant alleles in the genotype of organisms, phenotypes appear the same even though they differ in the genotypes.

What is the phenotype of a plant with the genotype WW?

The genotype for the pink flower is RW, and the genotype for the white flower is WW. This would lead to a 50 percent chance of the offspring having a phenotype of pink.

Why can individuals with different genotypes have the same phenotype quizlet?

The masking of recessive alleles can result in organisms with the same phenotype but different genotypes. Organisms with two dominant alleles (homozygous dominant and one recessive allele (heterozygius).

Is PP genotype or phenotype?

There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).

How can twins have different phenotypes?

Even monozygotic twins, who are genetically identical, always have some variation in the way they look and act. This uniqueness is a result of the interaction between our genetic make-up, inherited from our parents, and environmental influences from the moment we are conceived.

How does a genotype relate to a phenotype?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

Does genotype determine phenotype?

Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.

What does an organism’s genotype describe quizlet?

What does an organism’s genotype refer to? The combination of genes and alleles in an individual. Genotype refers to the particular combination of. genes or alleles that an individual. carries.

How do genotype and phenotype work together?

Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). To consider these in the context of evolutionary biology, we want to know how these two are related.

What does an organism’s phenotype describe quizlet?

phenotype. An organism’s physical appearance. genotype. An organism’s genetic makeup, or allele combinations.

What does an organism’s phenotype describe Brainly?

Explanation: Phenotype, all the observable characteristics of an organism that result from the interaction of its genotype (total genetic inheritance) with the environment. Examples of observable characteristics include behaviour, biochemical properties, colour, shape, and size.

What is the difference between heterozygous and homozygous individuals?

Homozygous and heterozygous are terms that are used to describe allele pairs. Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous.

What is the genotype for a heterozygous pea plant for round and green seeds?

Complete answer:

A pea plant with yellow round seeds is crossed with another plant with green wrinkled seeds. The genotype of yellow round seeds is YYRR and the genotype of green wrinkled seeds is yyrr.

What is the phenotype of a plant with the genotype RR quizlet?

What is the phenotype of a plant with a genotype of RR? In snapdragons, flower color is controlled by incomplete dominance. The two alleles are Red (R) and White (W). The heterozygous genotype is expressed as pink.

What happens when two homozygous plants are crossed?

When true-breeding, or homozygous, individuals that differ for a certain trait are crossed, all of the offspring will be heterozygous for that trait. If the traits are inherited as dominant and recessive, the F₁ offspring will all exhibit the same phenotype as the parent homozygous for the dominant trait.

What are the differences between genotypes and phenotypes?

The genotype refers to the genetic material passed between generations, and the phenotype is observable characteristics or traits of an organism.

How do different alleles produce different phenotypes?

Alleles produce phenotypes (or physical versions of a trait) that are either dominant or recessive. The dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype.

What is genotype in genetics?

In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.

Do identical twins have the same genotype?

Identical twins share the same genotype, since their genomes are identical; but they never have the same phenotype, although their phenotypes may be very similar. This is apparent in the fact that close relations can always tell them apart, even though others might not be able to see the subtle differences.

How is genotype expressed?

The genotype is the combination of alleles (gene forms) and the phenotype is the trait or enzyme produced from the genotype. The phenotype is determined by the genotype. Below, we see the genotype listed on the lefthand column and the phenotype listed in the righthand column as well as in the corresponding images.

How can identical twins with identical genetic make up end up looking different to each other?

As a result of the environment, chemicals called “epigenetic marks” attach to the chromosomes and can turn specific genes on or off. So identical twins with identical DNA may have different genes turned on, causing them to look and act differently, and even to develop different diseases such as cancer.

Why do genetically identical twins have different phenotypes?

From the epigenetic point of view, phenotypic disease differences in MZ twins result from their epigenetic differences. Due to the partial stability of epigenetic signals, a substantial degree of epigenetic dissimilarity can be accumulated over millions of mitotic divisions of cells of MZ co-twins.

How can one genotype produce different phenotypes?

Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.

What factors could cause individuals with the same genotype to express different phenotypes?

Dominance relationships between alleles for a given trait can impact phenotypic ratios, but interactions between different genes can also impact phenotype. Such traits that result from the interaction among multiple genes and their environment are called complex traits.

How are genotype and phenotype related quizlet?

What is the relationships between genotype & phenotype? Genotype refers to the alleles you possess for a particular gene or set of genes. Phenotype is the physical trait itself, which may be influenced by genotype and environmental factors.

Why might genetically identical twins have different phenotypes quizlet?

They may have different phenotypes because of differences in their environments, such as nutrition and healthcare. Why might genetically identical twins have different phenotypes? List three patterns of inheritance that are different than the dominant-recessive pattern of Mendel’s peas.

How does phenotype and genotype affect crop production?

By establishing the connection between genotype and phenotype, it is possible to improve agricultural production to satisfy the requirement of the growing human population. Therefore, phenotyping is as important as genotyping in establishing the relationship between genes and traits.

When a chromosome has two identical alleles for a given trait What is it?

Homozygous also refers to a genotype consisting of two identical alleles of a gene for a particular trait. An individual may be homozygous dominant (AA) or homozygous recessive (aa).

Which term describes an organism that has two identical alleles for a trait?

An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene.

What is an organism that has two identical alleles for a trait?

Homozygous: Having two identical alleles for a trait.

How can two plants that have different genotypes have the same phenotype?

Mandira P. Same phenotype but different genotype is possible due to presence of dominant allele. A dominant allele , when present in genotype, always expresses itself: both in double dose and in single dose.

What are the genotypes of the offspring?

An offspring’s genotype is the result of the combination of genes in the sex cells or gametes (sperm and ova) that came together in its conception. One sex cell came from each parent. Sex cells normally only have one copy of the gene for each trait (e.g., one copy of the Y or G form of the gene in the example above).

What is the genotype of a person’s trait of an organism?

An organism’s genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).

When the genotype consists of a dominant and a recessive allele?

When there is a genotype that consists of a dominant and a recessive allele, the phenotype generally looks like the dominant one.

How do dominant and recessive genes differ?

The main difference between dominant and recessive genes is that the dominant genes always express the dominant trait whereas the recessive genes express the recessive trait.

What is the difference between dominant and recessive traits?

What is the difference between dominant and recessive traits? Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.

What is the difference between homozygous and homogeneous?

Homogeneous and Heterogeneous is different from Homozygous and Heterozygous. On the other hand Homozygous and Heterozygous we use in taking about zygosity. Zygosity is the degree of similarity of the alleles for a trait in an organism. When Homo as you it refers ‘same’ and like this hetero which refers ‘different’.

What is the genotype of the heterozygote?

The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

What is the genotype produced when a pea plant that is purebred for yellow and round seeds YYRr is crossed with a pea plant that has green and wrinkled seeds YYRr )?

So, the correct answer is ‘YYRr‘.

How does a homozygous round seed plant differ from a heterozygous round seed plant in the F2 generation?

How does a homozygous round seed plant differ from a heterozygous round seed plant in the F2 generation? The round seed heterozygote has a genotype with two different alleles (Rr) while the round seed homozygote has the same allele (RR).

What method in genetics is used to cross between two individuals that are both heterozygous for two different traits?

Dihybrid cross is a cross between two individuals with two observed traits that are controlled by two distinct genes.

What happens when cross 2 heterozygous?

The expected genotype ratio when two heterozygotes are crossed is 1 (homozygous dominant) : 2 (heterozygous) : 1 (homozygous recessive). When a phenotypic ratio of 2 : 1 is observed, there is probably a lethal allele.

What genetic phenomenon occurs when a heterozygote shows a different effect than a homozygous dominant individual?

In particular, the phenomenon known as overdominance occurs when a heterozygote has a more extreme phenotype than that of either of its parents.

How does genotype differ from phenotype quizlet?

What is the difference between genotype and phenotype? The phenotype is an organism’s physical appearance, and the genotype is the genetic makeup.

What are the different genotypes?

A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.

What is the phenotype of a plant with the genotype R R?

When ever the R gene is present in the genotype of a plant, the flower color is always red. The mutant form of this gene, which is recessive, is often written r. Plants with the genotype RR or Rr have red flowers.

What is the phenotype of a plant with the genotype RW?

Correct! The genotype for the pink flower is RW, and the genotype for the white flower is WW. This would lead to a 50 percent chance of the offspring having a phenotype of pink.
