Question

Two plants, both heterozygous for the gene that controls flower color, are crossed. What percentage of their offspring will have purple flowers?

Answer 1

Explanation:

Do you know where each letter (allele) in all four cells comes from? Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio. Or, about 75% of the offspring will be purple.
