Question

a plant contains the alleles gg for green pod color. it is crossed with a plant that has the alleles gg for yellow pod color. the offspring have green pods. what is the allele combination?

Explanation:

Step1: Determine gametes

The first plant (Gg) can produce gametes G and g. The second plant (gg) can only produce gamete g.

Step2: Do the cross

Using Punnett - square method:

	G	g

Since the offspring have green pods (dominant trait), and green is dominant over yellow. The allele combination for green pods in the offspring is Gg.

Answer:

Gg
