How can two organisms have the same phenotypes but different genotypes?
Due to the presence of a dominant allele, the same phenotype but distinct genotype is possible. A dominant allele always expresses itself when it is present in the genotype.
How can they both have the same phenotype but different genotypes in coat color?
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.
How is it possible that organisms with the same phenotype can have different genotypes 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).
What is the genotype of a pea plant that’s homozygous for height?
| Genotype | Definition | Example |
|---|---|---|
| Heterozygous | One dominant allele and one recessive allele | Tt |
| Homozygous dominant | Two dominant alleles | TT |
How can two pea plants that have different genotypes have the same phenotype?
| Genotype | Definition | Example |
|---|---|---|
| Homozygous | Two of the same allele | TT or tt |
| Heterozygous | One dominant allele and one recessive allele | Tt |
Which describes the genotype of the pea plant?
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).
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 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.
How does a genotype become a phenotype?
Genotype & Phenotype. Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment).
Is it possible for two tall pea plants to produce a short pea plant variety explain?
The “TT” and “Tt” crosses both have at least one “T” allele, so they are tall plants. However, the last cross “tt” doesn’t have any “T” alleles and is short, because it is homozygous recessive . Since 1 out of 4 pea plants are short, or 1/4, the probability of a short pea plant from a heterozygous cross is 25%.
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 are the genotypes of a homozygous and a heterozygous tall pea plant?
This makes the inheritance easy to observe and follow. What are the genotypes of a homozygous and a heterozygous tall pea plant? DD is homozygous dominant, gives phenotype tall. Dd is heterozygous, also gives the phenotype tall.
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.
How will you determine the genotype of given pea plant bearing yellow seeds and violet flower?
Answer: if the offspring produced by the test cross is 50% purple and 50% white flower then the genotype of the purple flower pea plant is heterozygous dominant (Pp). If all the flower produced is purple coloured then the genotype of the purple flower is homozygous dominant (PP).
Which are different forms of the same gene genotypes?
Different versions of the same gene are called alleles. Genes can have two or more possible alleles. Individual humans have two alleles, or versions, of every gene.
What are the two genotypes that show the dominant phenotype?
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.
Can you have the same genotype but different phenotype?
The same genotype, when raised in different environments results in different phenotypes. Furthermore, different genotypes respond to the same environmental changes differently from each other.
What are two genotypes?
A particular genotype is described as homozygous if it features two identical alleles and as heterozygous if the two alleles differ. The process of determining a genotype is called genotyping.
Is phenotype determined by genotype?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
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.
What is the relationship between genotypes and phenotypes?
The genotype of an organism is defined as the sum of all its genes. The phenotype of an organism is the observable physical or biochemical characteristics of an organism, determined by both genetic make-up and environmental influences.
What is the genotype for a homozygous dominant pea plant?
A true-breeding tall pea plant would have the genotype with two dominant alleles, usually represented as TT .
How would you determine the genotype of a tall pea plant?
To know the genotype of the plant, a test cross is performed. In the test cross, pea plant showing the dominant phenotype is crossed with the pea plant that is homozygous recessive for the same trait. Results of the test cross are then interpreted to know the exact genotype of the given plant.
What is the genotype for the tall plant?
Genotypes for plant height are TT, Tt, tt. Genotypes can be heterozygous or homozygous. Phenotypes for plant height are tall or short. TT and Tt genotypes both expressed the tall phenotype because the T is dominant to t.
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.
Which genotype consists of two identical genes for a given character?
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). Individuals who are homozygous for a trait are referred to as homozygotes.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
What are 3 examples of genotype?
- Hair color.
- Height.
- Shoe size.
How did Mendel control pollination in pea plants?
Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice.
Why did Mendel choose pea plant for his experiment write two reasons?
Mendel choose pea plants for his experiments because of the following reasons: (i) The flowers of this plant are bisexual. (ii) They are self-pollinating, and thus, self and cross-pollination can easily be performed. (iii) The different physical characteristics were easy to recognize and study.
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 are the genotypes of the individuals labeled 1/2 and 3?
What are the genotypes of the individuals labeled 1, 2 and 3? Individual 1 has the genotype aa. Individual 2 has the genotype Aa. Individual 3 has the genotype Aa.
How would you find out the genotype of a pea plant with violet flower explain with the help of?
To determine the genotype of the pea plant with purple flowers the students can use the process of Test cross. In test cross the pea plant whose genotype is to be determined is crossed with a homozygous recessive parent (pp) having white flowers.
What would be the genotype of the parents if the offspring have the genotype in 1 1 1 1 proportion?
Alternative (D) Aa x aa is correct option. If the offspring have the phenotypes in 1:1 proportion then genotype of the parents will be Aa x aa.
What will be the genotype of a tall pea plant with violet flower?
All tall and violet, then genotype of parent is TTWW.
What is the genotype of a pea plant that’s homozygous for height?
| Genotype | Definition | Example |
|---|---|---|
| Heterozygous | One dominant allele and one recessive allele | Tt |
| Homozygous dominant | Two dominant alleles | TT |
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.
What represents homozygous genotypes?
The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.
How can you determine the genotype of a plant showing the dominant phenotype of red color?
How can you determine the genotype of a plant showing the dominant phenotype of red color? The phenotype reflects the genotype, so the plant must be homozygous for the trait. Cross the red plant with a white plant to see if any white plants appear.
How do you determine genotypes?
The possible pairs of alleles for one parent is written down the left side of the table, and the alleles of the other are written across the top of the Punnett square. The same process is used to determine the possible genotypes and phenotypes of the offspring.
What is the only genotype that shows the recessive phenotype?
The recessive phenotype is controlled by the homozygous aa genotype.
What are the three possible genotypes for flower color in pea plants?
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).
What is genotype in plants?
The genotype of a plant is a word used describes the genetic make – up of the plant. The context that it is used depends upon whether it is being used to describe the whole genome, the DNA sequence of individual genes or a collection of scores at different genetic markers.
How many phenotypes can be expressed?
There are three common alleles in the ABO system. These alleles segregate and assort into six genotypes, as shown in Table 1. As Table 1 indicates, only four phenotypes result from the six possible ABO genotypes.
How do changes in genotype affect phenotype?
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.
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.
Why can different phenotypes arise from the same genotype?
Phenotypic variation can be produced by genetic differences, environmental influences and stochastic developmental events.
