Q: If you cross a purebred pea plant with green seeds and a purebred pea plant with yellow seeds what percent of their offspring will have green seeds

If you cross a purebred pea plant with green seeds and a purebred pea plant with yellow seeds what percent of their offspring will have green seeds

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.
