Calculate the probability of homozygous dominant offspring result from a cross between two heterozygous parents

1/4. Make a Punnett square and plug in the two heterozygous genotypes of the parents, put them together and you get the following possible genotypes: AA, Aa, Aa, and aa. One of those is homozygous dominant. 1/4 or 25 percent.
