Assuming complete dominance, what is the expected ratio of phenotypes of the offspring following the cross of two heterozygotes?
A)4:1
B)1:1
C)3:1
D)1:2:1

Question

Quizplus · Accepted Answer

When two heterozygotes are crossed in a complete dominance scenario, the expected phenotypic ratio of the offspring is 3:1. This means that for every 4 offspring, 3 will express the dominant phenotype and 1 will express the recessive phenotype. This is because the dominant allele masks the expression of the recessive allele in heterozygotes.
