Question

which diagram correctly shows how homozygous alleles are found on homologous chromosomes? aa aa

Explanation:

Homologous chromosomes are pairs of chromosomes, one from each parent. Homozygous alleles mean that the two alleles at a particular gene locus are the same. In the first diagram, the alleles are "Aa" (heterozygous - different alleles). In the second diagram, the alleles are "aa" (homozygous - same alleles).

Answer:

The second diagram (with "aa" alleles) correctly shows homozygous alleles on homologous chromosomes.
