Question

In pea plants, green pods are dominant to yellow pods and round seeds are dominant to wrinkled seeds. If a plant that is heterozygous for green pods and has wrinkled seeds is crossed to a plant that has yellow pods and is heterozygous for round seeds, what is the probability of getting an offspring that has yellow pods and wrinkled seeds?

Answer 1

25% of the probabillity

To know what's happened here, we need to draw a Punnett square crossing both characteristics at the same time.

First, we need to identify the alleles:

Green is dominant over yellow: G and y

Rounded is dominant over wrinkled: R and w

So, if we have a plant that is heterozygous for green pods and has wrinkled seeds (Gy ww) is crossed to a plant that has yellow pods and is heterozygous for round seeds (yy Rw) its offsprings will be:

1/4 green round: Gy Rw

1/4 yellow round: yy Rw

1/4 green wrinkled: Gy ww

1/4 yellow wrinkled: yy ww
