What is the chance that a man with type AB blood and a woman with type A blood whose mother is type O can produce a child that is:

Two parents with blood types AB and B have a child who has A blood type. What is the chance that their next child will be blood type O?   a 0 b 1/2 c 1/4 d 1 e 3/4

If a man with type O blood has a child with a woman who has type AB blood, what are the possible blood types for the child?

A woman with type O blood gave birth to a baby, also with type O blood. The woman stated that a man with type AB blood was the father of the baby. Is there any merit to her statement?

Sickle cell anemia is an inheritable red blood cell disorder that results in sickle-shaped red blood cells. The sickle-shaped red blood cells can stick to blood vessel walls and cause a blockage or slow the movement of blood throughout the body.   Individuals who are heterozygous produce both normal and sickle-shaped red blood cells which gives them resistance to malaria but they do not develop sickle cell anemia (so heterozygotes are unaffected on the pedigree).Let HbS be the allele for sickle cell anemia and let HbA be the allele for normal red blood cells.   Which of the following rows provides the correct genotypes for individuals I-2, I-4, II-1, and III-1? Select one: a. I-2 I-4 II-1 III-1 HbA_ HbAHbS HbAHbS HbA_ b. I-2 I-4 II-1 III-1 HbA_  HbAHbS HbAHbS HbAHbS c. I-2 I-4 II-1 III-1 HbAHbS HbAHbS HbAHbS HbAHbS d. I-2 I-4 II-1 III-1 HbAHbA HbAHbA HbAHbA HbAHbA

Hemophilia A is caused by a recessive X-linked allele that encodes a defective form of a clotting protein. If a affected father and a mother who is known to not be a carrier have children, what percentage of female offspring will have hemophilia?

If a girl has blood type B and her mother has blood type A, what genotype(s) and corresponding phenotype(s) could the other parent have?

Is it possible for any sonof a couple formed by ahemophilic man (XhY) and anonhemophilic noncarrier(XX) woman to be hemophilic?

A couple with the following blood types: the man has type AB and the woman has type B, discover their child has type O blood.    Is it possible that one of these ‘parents’ may not actually be the genetic parent of this child?  If so, which one, and how do you know?
