Assume a phenotype is determined by one gene with a dominant allele and a recessive allele.If one parent is homozygous dominant (AA)and the other parent is homozygous recessive (aa),what genotype(s)might their offspring have?

Question

Quizplus · Accepted Answer

The dominant allele (A) will always be expressed in the presence of the recessive allele (a). When one parent is homozygous dominant (AA) and the other parent is homozygous recessive (aa), all of the offspring will inherit one copy of the dominant allele and one copy of the recessive allele (Aa). They will all exhibit the dominant phenotype because it only takes one copy of the dominant allele to express the trait. Therefore, the only possible genotype for the offspring is Aa.
