Then the father of the child is someone else with B Negative blood group.
because the dad blood was stronger and one positive and one negative make a positive
Yes, if the father's genotype is AO, and both of them have +- genotype. However, this would be very rare.
50% chance of A. 50% chance of B. either positive or negative(shruggs). If the child is AB the mother screwed around on the 'dad' If the child is O you did the test wrong, because their is no way the woman can be wrong about whether or not the baby came out of her
Maybe. A child will have either the mother's blood type or the father's blood type. If the father is B+ and the mother is A- then it is possible that the children have the same father. So it all depends on both parent's blood type.Source: I am a 2nd year nursing student, and we had a long discussion about this subject last semester.
YES. Blood type is determined by two alleles. An "A" individual can be homozygous "AA" or heterozygous "AO" and still be considered type A. The same is true of a "B" individual. If the father is "AO" and the mother is "BO" then statistically, they have a 25% chance of having a child that is "OO" or type O.
No, they cannot.
No, they cannot.
Yes. A negative Rh factor is recessive. Everyone has 2 copies of this gene (one from mom, one from dad.) Since positive is dominant and negative is recessive, if you have one of each (heterozygous), you will have a positive blood Rh, but sitll carry the gene for negative Rh. If this is the case for both parents, then the child has a 25% chance of being Rh negative.
because the dad blood was stronger and one positive and one negative make a positive
Negative is recessive...you can have a negative also.
it is rh negative and rh positive that u dont want to mix not the a b o types it is the + or - two ++ mom n dad or two -- mom n dad not 1 positive(+) and 1 negative(-)
no
yes
Yes, if the father's genotype is AO, and both of them have +- genotype. However, this would be very rare.
no
yes
No. The mother must be either AO or AA, and the father OO. No combination of these can give rise to an AB child. However, a negative mother and a positive father can have a negative child, by rhesus factors, if the father has genotype +-.
