What is the probability for the possible phenotypes that result from the cross of two heterozygous parents (Aa and Aa)? (The A allele is for normal pigmentation, and the a allele is for albinism.)

Question

Quizplus · Accepted Answer

The cross of two heterozygous parents (Aa x Aa) results in a 3:1 ratio of phenotypes in their offspring, where 75% show the dominant phenotype (normal pigmentation) and 25% show the recessive phenotype (albinism). This is because the possible genotypes are AA, Aa, Aa, and aa, with the first three having normal pigmentation and the last one being albino.
