The couple visits a geneticist to determine what the possible risks are for their future children. The couple discovers that the mom is a carrier, or heterozygous with the diabetes allele and the dad is homozygous dominant, so neither of them have the disease but the mom has one recessive allele. In order to have Diabetes, you have to have two recessive alleles. The following year, the parents are blessed with a bouncing baby boy! What is the correct genotype of the mom?
