Pea plants produce flowers that have one of two colors: Purple or white. The locus for the gene that produces that pigment in pea plants has two alleles. The P1 allele codes for purple color while the P2 allele codes for white color. Plants that are homozygous for the P1 allele as well as heterozygotes produce purple flowers while homozygotes for the P2 allele produce white flowers. If the frequency of individuals of individuals in a pea plant population that are homozygous for the P1 allele is 0.49 and assuming the population is in Hardy-Weinberg equilibrium, what would be the frequency of: Homozygotes for P2 Heterozygotes

Step 1
In Hardy-Weinberg equilibrium, the sum of the frequencies of all genotypes must equal 1. Given that the frequency of homozygotes for P1 allele (P1P1) is 0.49, we can calculate the frequency of P1 allele (P) as follows: P1P1 = P^2 = 0.49 P = sqrt(0.49) = 0.7 Since Show more…

In pea plants, the allele for purple flowers (P) is dominant and the allele for white flowers (p) is recessive. The allele for yellow seeds (Y) is dominant and the allele for green seeds (y) is recessive. The allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive. These alleles segregate independently of each other. A plant with a PpYyRr genotype is crossed with a plant with a PpyyRr genotype. What is the probability that an offspring from this cross has at least two different recessive traits?
Jackson M.
Flower color in the varieties of pea plants studied by Mendel is controlled by alleles at a single locus. A group of peas homozygous for purple flowers is grown. Careful study of the plants reveals that all their flowers are purple, but there is some variability in the intensity of the purple color. What would the estimated heritability be for this variation in flower color? Explain your answer.
