Question

practice identifying dominant and recessive alleles
a homozygous genotype can show either a dominant or a recessive trait, because both of the alleles are the same. an example of a homozygous dominant genotype is aa. an example of a homozygous recessive genotype is (need a refresher? watch this video on heterozygous and homozygous)
possible points: 0.63

Explanation:

Step1: Recall Genotype Definitions

A homozygous recessive genotype has two identical recessive alleles. From the options (AA, Aa, aa), aa has two recessive (a) alleles.

Step2: Identify the Genotype

Among AA (homozygous dominant), Aa (heterozygous), and aa (homozygous recessive), the homozygous recessive is aa.

Answer:

aa
