Question

In garden pea plants, the allele for green pod colour, G, is dominant over that for yellow pod colour, g. Consider a cross between a garden pea plant that is homozygous for green pod colour and a plant that is homozygous for yellow pod colour. What is (are) the only possible phenotype(s) of the offspring?

Answer 1

All offspring will have green pods.
Each is genotype Gg (heterozygous), and the dominant G allele produces the green-pod phenotype in 100% of the progeny.
