Q: What would happen to the probabilities of yellow and green seeds if one parent were homozygous recessive and the other were homozygous dominant?

What would happen to the probabilities of yellow and green seeds if one parent were homozygous recessive and the other were homozygous dominant?

Flexi Says: YY genotype can only produce gametes with a Y allele, and the yy genotype can only produce gametes with a y allele. In peas, yellow seeds (Y) are dominant over green seeds (y). In this cross of YY x yy, you would expect all (100%) of the offspring to have yellow seeds with heterozygous (Yy) genotype.
