If you mate a homozygous dominant individual with a homozygous recessive individual, what will be the genotype of the F1 generation?

Homozygous dominant

Homozygous recessive

Heterozygou

Mixed genotype

When a homozygous dominant individual mates with a homozygous recessive individual,

their offspring will all be heterozygous for that particular trait.

This results in a genotype of heterozygous (Aa) for all offspring.

Since the dominant allele masks the effect of the recessive allele, the phenotype of the F1 generation will exhibit the dominant trait.
