Blood Type Problems - 12th Grade Anatomy and Physiology
A man of unknown genotype has type B blood, his wife has tpe A blood (also unknown genotype). List ALL the blood types possible for their children. (You may need to do multiple crosses to consider the different possib;e genotypes of the parents).
Blood types A, B, AB, and O
A person has type B blood. What are ALL the possible blood types of his parents? Show the crosses to prove your answer.
Blood types A, B, AB, and O
A person with type B blood (genotype BO) has children with a type AB person. What blood types are possible among their children?
Blood types A, B, and AB
Two people, both with AB blood, have four children. What blood types should the children be?
Blood types A, B, and AB
A person with type A blood (unknown genotype) marries a person with type O blood. What blood types are possible among their children? (Show 2 crosses)
Blood types AO and O
A person with type O blood is married to a person with type A blood (unknown genotype). They have 6 children; three of them have type A blood, three of them have type O blood. What is the genotype of the two parents?
Genotypes OO and AO
A man with type AB blood is married to a woman with type O blood. They have two natural children, and one adopted child. The children's blood types are: A, B, and O. Which child was adopted?
The child with type O blood.
Why is a person with type AB blood called a "universal acceptor"?
They're called that because they have all antigens.
Why is a person with type O blood called a "universal donor"?
They're called that because type O blood doesn't have any surface antigens; therefore, it doesn't produce any antibodies to attack.
Two people with type O blood have three children. How many of those three children also have type O blood?
Three-- they all have type O blood.
A woman with type A blood (genotype: AO) is married to a type B person (genotype: BO). What blood types will their children have?
Type A : 25% Type B : 25% Type AB : 25% Type O : 25%
A man with AB blood is married to a woman with AB blood. What blood types will their children be and in what proportion?
Type A : 25% Type B : 25% Type AB: 50%
A man who has type B blood (genotype: BB) is married to a woman with type O blood. What blood type will their children have?
Type B blood (genotype: BO)
List all the possible genotypes for each of the 4 blood types: Type O: Type A: Type B: Type AB:
Type O : OO Type A : AO & AA Type B : BO & BB Type AB : AB
A woman with type A blood is claiming that a man with type AB blood is the father of her child, who is also type AB. Could this man be the father? Show the possible crosses; remember the woman can have AO or AA genotypes.
Yes
