Question

which of the following pairs of alleles are heterozygous for the trait? mark all correct answers a. aa b. gg c. aa d. gg

Explanation:

Heterozygous means having two different alleles for a particular gene. In genetics, if an allele pair has two different forms (e.g., one dominant and one recessive), it is heterozygous. For example, in "Aa", there is one dominant allele (A) and one recessive allele (a). Similarly, in "Gg", there is one dominant allele (G) and one recessive allele (g). On the other hand, "GG" and "aa" have two of the same alleles (homozygous).

Answer:

A. Aa, D. Gg
