In peas, yellow seed color (Y) is dominant to green seed color (y). Which describes an organism that has nonidentical alleles for seed color? A. yy and has green seeds B. Yy and has yellow seeds C. YY and has yellow seeds D. Yy and has green seeds

The correct answer is B. Yy has yellow seeds.

Yy they are heterozygous which means that their alleles are identical.

Yellow seeds are dominant are green so the plant should be yellow in color and both alleles are present.

Yellow dominates on green that is why we say that the pea seeds are green.

B because it is heterozygous, meaning its alleles aren't identical, and the plant must be yellow, because yellow is dominant over green when both alleles are present.
