Question

find out the possible blood groups and genotypes of the children of following parents
a. Mr.x = O group
Mrs.x= B group

b. Mr.y= A
Mrs.y = AB

c. Mr.z= A
Mrs.z= A ​

Answer 1

Answer:

Yes. Its possible.

Let mother be AO.

Let father be BO.

The combination an offspring can have:

AB, AO, BO and OO.

Since O is recessive while the other two are dominant, the first three cases mentioned will lead to Blood Group, AB, A and B respectively. But the last case is O.

Note: If any one of the parent has pure A, i.e AA or pure B, i.e. BB, the offspring can't be of blood group O.

Problem c:. Mother is type A and father is type A

Mrs. Brown AB Mrs. Smith A

Mr. Brown B Mr. Smith B

Babies: Baby 1 is type O… Baby 2 is type A
