What blood types is not possible from the male having AB and female with AO?

Question

What blood types is not possible from the male having AB and female with AO?

Answer 1

Type O is not possible it is recessive.  Only children of parents who are both type O can be type O.

Answer 2

O would be the blood type not possible

Each parent has to give one allele to it's offspring.

The male in this cross can give either A or B, but not both.

The female in the cross can give either A or O, but not both.

O is recessive to both A and B alleles, and A and B are codominant to each other.

Possible genotypes from the above male and female are:

AA and AO, which would give the phenotype of Blood type A,

AB which would give the phenotype of Blood type AB, and

BO which would give the phenotype of Blood type B

Answer 3

Type O is not possible.

Answer 4

male is AB (has allele A and alelle B)

female is AO (has allele A and alelle O)

if you work out the combinations in a punnit squares:

AB x AO

_______A_____B____

A _____AA____AB

O ____ AO ____BO

so you can have

AA ...which is blood type A

AO...which is blood type A (A is dominant)

AB ...which is blood type AB (A and B are co-dominant)

BO...which is blood type B (B is dominant)

So you cannot have blood type O (in order to be blood type O you would need both recessive OO alleles - one from male and one from female)                        

Answer 5

There's no such blood type as "AO".....

If you mean that the female is heterozygous for blood type A, then blood type O is not possible.

If the female is homozygous for blood type A, then blood types B and O are not possible.

If the female has blood type O, then blood types AB and O are not possible.
