A person with type O blood marries a person with type AB blood. Possible blood genotypes of their children are
|
|
I(A)i and I(B)I(B)
|
|
|
I(B)I(B) and I(A)I(A)
|
|
|
I(A)i and I(B)i
|
|
|
I(A)I(B) and ii
|
Explanation:
Detailed explanation-1: -A man with type O blood would not be able to produce a child with type AB blood regardless of the mothers blood type. This is because type O blood is recessive and these individuals have two O alleles so the only allele they would be able to pass to a child would be “O".
Detailed explanation-2: -The different possible genotypes are AA, AO, BB, BO, AB, and OO. How are blood types related to the six genotypes? A blood test is used to determine whether the A and/or B characteristics are present in a blood sample.
