homozygous recessive, aa

A heterozygous parent gives 50% of the offspring a dominant allele and 50% of the offspring a recessive allele. In order for the 50% that receive the recessive allele from parent B to be homozygous recessive, 100% of the alleles from parent A must be recessive (homozygous recessive).
