Biology: In pea plants there is a dominant allele (A) for green pods and a recessive allele (a) for yellow pods. Suppose a heterozygous plant is crossed with a plant that has yellow pods. Complete the sentences about this monohybrid cross with the correct terms. The phenotype of the heterozygous plant is The genotype of the heterozygous plant is The genotype of the plant with yellow pods is The genotype of the gametes produced by the heterozygous plant is The genotype of the gametes produced by the plant

Answer and Explanation:

The phenotype of the heterozygous plant is green podsThe genotype of the heterozygous plant is AaThe genotype of the plant with yellow pods is aaThe genotype of the gametes produced by the heterozygous plant is 50% A 50% aThe genotype of the gametes produced by the plant with yellow pods is 100% a The expected frequency of F_1 plants with yellow pods is 50%The expected frequency of F_1 plants with the genotype AA is 0%

Cross) a heterozygous plant is crossed with a plant that has yellow pods

Parental) Aa x aa

Phenotype) Green pods Yellow pods

Gametes) A a a a

50% 50% 100%

Punnet Square) A a

a Aa aa

F1) 2/4 = 1/2 = 50% Aa, Plant with Green pods

2/4 = 1/2 = 50% aa, Plant with Yellow pods
