7. Below is a pedigree for a family in which some members have achondroplastic dwarfism, This trais is inherited as an autosomal dominant. Individuals shaded on the pedigree have achondroplastic dwarfism. The homozygous dominant condition usually results in death in-utero. Complete the chart indicated relationship and whether both, one or neither has achondroplastic dwarfism.

Sickle cell anemia is inherited as an autosomal recessive condition. It also exhibits incomplete dominance in that the heterozygous genotype displays a mild form of the disease known as sickle cell trait while individuals with the homozygous recessive genotype have a severe form of SCA. A man who has severe sickle cell anemia marries a woman who suffers from a mild trait. What is the probabilitu they will have a child with severe SCA?What is the probability they will have a child with mild SCA? What is the probability they will have a normal child?
