Using a genetic diagram, identify the genotypes of the F2 generation of pea pods if a homozygous green pod and a homozygous yellow pod were crossed initially. The yellow pod contained recessive alleles (g).

A homozygous green pod will have a GG genotype while a homozygous yellow pod will have gg. Each parent has two alleles but only one is passed to an individual offspring via the gametes. In this case, the pos...
