Understand the concept of homozygous genotypes: A homozygous genotype consists of two identical alleles for a particular gene. This can be either two dominant alleles (AA) or two recessive alleles (aa).
Examine the given genotypes: The genotypes provided are AaBb, Aa, aa, and AA.
Identify the homozygous genotypes: Look for genotypes where both alleles are the same. In this case, aa and AA are homozygous because they consist of two identical alleles.
Differentiate between homozygous and heterozygous: A heterozygous genotype consists of two different alleles for a gene, such as Aa or Bb.
Conclude which genotypes are homozygous: Based on the definition, the genotypes aa and AA are homozygous.
