In pea plants how many alleles for seed color does each parent pass to each offspring?

That is to say, they each had two identical forms (or alleles ) of the gene for this trait--2 yellows or 2 greens. The plants in the f1 generation were all heterozygous . In other words, they each had inherited two different alleles--one from each parent plant.
