Determine the genotypes of the parents if the father is blood type A the mother is blood type B the daughter is blood type O one

antoniya [11.8K]

Answer:

The genotypes of father will be iA i

and of mother will be iB i

Explanation:

CASE I: If father's genotype is iA iA

and mother's genotype is iB iB

This case is not possible because daughter has 'O' blood group.

CASE II: If father's genotype is iA iA or iA i

and mother's genotype is iB i or iB iB

This is also not possible because 'O' blood group will not appear in any crossing.

CASE III: If father's genotype is iA i

and mother's genotype is iB i

in this case both 'AB' and 'O' blood group is possible.

hence, father's genotype is iA i

and mother's genotype is iB i.
