Yes. If the mother and father both carry O blood type it will be hidden by their A and B blood types. The same goes for the Rh factor the negative can still be carried by the parents but again will be hidden. They can pass these genes to their children.
Given that the mother's DNA is A and the child is A positive, the father's DNA must also contain the A antigen. The father could be A positive, A negative, AB positive, or AB negative.
No. The child will be type O+ or O-.
Yes. The father's phenotype is AO+*; the mother's is OO--.
for sure
yes it dependsupon the genotype and phenotype
No. They can have an O positive, an O negative, A B positive, or a B negative child.
no
o positive
yes
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
Given that the mother's DNA is A and the child is A positive, the father's DNA must also contain the A antigen. The father could be A positive, A negative, AB positive, or AB negative.
If mother is heterozygote yes.
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
no
no
if your child is negative, i would ask for a blood sample from the mailman
yes.
