no Yes. If the mother's phenotype is A, the mother's genotype may be AA or AO.
If the mother's phenotype is A, the mother's genotype may be AA or AO.
If both are AO, the baby may inherit O from both parents, and the baby's genotype will be OO, and the phenotype will be O.
A baby born to two parents who are genotype AO can have the following genotypes: AA, AO, OO. The possible phenotypes are therefore A or O.
The dad may be O...but maybe not. It used to be believed that was the end of the story. But they now know that the blood type can be carried down from anywhere in the gene pool...which is why further testing is done for paternity. It goes much deeper than basic ABO and Rh type. In other words the great grandmother or the great great grandfather (on either side) may have been O and the father could be a B
Yes.
No, they cannot.
Mommy is a positive word
o
no
yes
No, they cannot.
yes I have o negative my husband has o positive; I have daughter with o negative and a son with o positive
This can be figured out by using a blood type punnet square, a simple form of genetic engineering. However, this is physically impossible for two parents of "o" blood types to have a son/daughter of blood type "a." You are either adopted, or one of your parents is not your original parent.
of course.
yes
I believe, not certain though, that you are either O pos or O neg
