Question

Quizplus · Accepted Answer

The only allele that affects the child's characteristics is called the dominant allele. This is because, in a dominant-recessive inheritance pattern, the dominant allele masks the effects of the recessive allele when both are present in an individual's genotype. Therefore, the dominant allele determines the expression of the trait. The recessive allele only affects the phenotype when present in a homozygous state (i.e., in the absence of a dominant allele). A carrier is an individual who has one copy of a recessive allele but does not express the trait because they also have a dominant allele.
