Detailed explanation-1: -The genotype of a woman with type A blood whose father has type O blood is AO. This is because the O blood allele is recessive and will only produce the O blood type of both alleles in a person are O.
Detailed explanation-2: -Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO.
Detailed explanation-3: -In order for a person to have type A blood, their genotype must be either AA or AO. A person must have inherited an A allele from at least one parent. They cannot have inherited a B allele from either parent.
Detailed explanation-4: -Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type. One parent with A and another with B can produce a child with A, B, AB or O blood types.
