What is the phenotype of a purple flower?
A pair of alleles—one from each parent—makes up the genotype for a trait. The way the trait appears is its phenotype. In pea plants, purebred purple flowers have a genotype with two purple alleles, which produces a phenotype of purple petals.
What is the phenotype of a flower?
The phenotype of a plant is a term used to describe observable characteristics, such as height, biomass, leaf shape and so on. We use the term phenotype in a more specific context to describe the collective expression of the genotype in conjunction with the environment on a plant’s observable characteristics.
What is purple genotype?
The genotype of the purple-flowered plant is PP. Since white flowers are recessive, the only possible genotype for a white-flowered plant is pp. As you can see, all of the offspring in Mendel’s first cross had a genotype of Pp. That’s why all of the plants in the p first generation had purple flowers.
What is the phenotype for color?
Genotype vs Phenotype: Examples and Definitions
| Genotype | Phenotype | |
|---|---|---|
| Depends on | The gene sequences an organism possesses | Genotype, PLUS epigenetics and environmental factors |
| Inherited? | Yes | No |
| Example | Genes encoding eye color | An individual with brown eyes |
Which genotype is possible for the phenotype purple?
B is dominant to b, so offspring with either the BB or Bb genotype will have the purple-flower phenotype. Only offspring with the bb genotype will have the white-flower phenotype.
What is the phenotype of a purple-flower pea plant quizlet?
If a recessive trait (like white flowers) is expressed in an organism’s phenotype, what can you determine about its genotype? If a pea plant has the dominant phenotype of purple flowers, what do you know about its genotype? In pea plants, purple flowers (P) are dominant to white flowers (p).
Is flower color a genotype or phenotype?
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 two possible phenotypes for flower color?
The phenotype can be either red or white flower color, depending on the genotype.
What is the phenotype of a purple flower pea plant quizlet?
What is the phenotype of purple flowers are dominant to white flowers?
Since all of the offspring have the purple phenotype, this tells us that the purple allele is dominant to the white allele. This means that 75% of the offspring displayed the dominant phenotype of purple flowers, and 25% displayed the recessive phenotype of white flowers.
Is DD heterozygous or homozygous?
| Individual | Genotype | |
|---|---|---|
| Sam (father) | DD | homozygous dominant |
| Sally (mother) | dd | homozygous recessive |
| Susan (child) | Dd | heterozygous |
Which is dominant allele for purple flowers, P?
In pea plants, the allele for purple flowers, P, is dominant over the allele for white flowers, p. Which conclusion about phenotype and genotype is possible? (1 point) If a plant has purple flowers, then its genotype must be Pp. If a plant has white flowers, then its genotype must be Pp.
Which is dominant purple flower or white flower?
Purple flower color is dominant to white flowers in pea plants. What is the genotype of a Purple Parent if the phenotypic ratio of the offspring is 50% Purple and 50% White. Hint – do a test cross. Dimples (D) is dominant to no dimples (d).
What is the ratio of purple offspring to white offspring?
If a purple flower with the genotype P p (P = purple ; p = white) self-pollinates, what is the ratio of purple offspring to white offspring? The flower is purple which means P is dominant (every time is in the flower will be purple). There are four possibilities: PP pP Pp pp, in the first 3 it will be purple and in the last it will be white.
Which is an example of a phenotype influenced by environmental factors?
Two examples of phenotypes influenced by environmental factors. 1. Hydrangea flower color and pH 2. Arctic fox fur color and temperature Purple flower color is dominant to white flowers in pea plants. What is the genotypic ratio of the offspring from two hetreozygous parents? Purple flower color is dominant to white flowers in pea plants.
