(B) Draw a Punnett square for a cross of a green-podded heterozygote plant with a yellow-podded plant. Then, draw a Punnett square for a cross of a green homozygous plant with a yellow-podded plant. For each cross: What are the genotype frequencies? What are the phenotype frequencies? Why is this a good test of the genetic status of the green plant? (3) Mendel studied dihybrid pea plants for seed shape (round versus wrinkled) and seed color (yellow versus green). Following the example and notation in the textbook, recall that - the round allele $(R)$ is dominant to the wrinkled allele $(r)$ and - the yellow allele $(Y)$ is dominant to the green allele $(y)$. The table below shows the $F_1$ progeny that result from selfing four different parent pea plants (i.e., crosses 1-4). Use the phenotypes of the $F_1$ progeny to deduce the genotype and phenotype of each parent plant. Write your answers in the boxes below.
