Read the scenario and use the information to help you answer the questions.
Disease Possibilities
A man and woman have decided to have children but are worried about possible genetic diseases. The couple visits a geneticist to determine what the possible risks are for their future children. The couple learns that they are both carriers (heterozygous) for Sickle Cell Disease. Each of them has one recessive allele. In order to have Sickle Cell Disease, you have to have two recessive alleles. The following year, the parents are blessed with a bouncing baby boy!
