Blood type does not prevent people from having children.
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
because some women want more than one child. Some religions/cultures see it as wrong if a woman has more than one child.
There were no women Survivors and Only One Child Survivor, The Rest Were Men.
Probably, because it only takes one positive gene to have positive type blood. But if the positive parents each have one positive and one negative gene, there is a 25% chance their child will be negative.
No. If both parents have a negative blood type, the child will either have the mother's blood type,or father's blood type, or if one parent is A- and the other B- only then can a child be born AB-. However, if two people with negative blood types try to have a baby, that may be very difficult. Sterility usually runs on the negative blood types, but conceiving a child is not impossible for them.
yes
Yes! Parents have two genes for pos/neg blood type, and only one of them needs to be positive for the parent to have positive blood type. Most positive-blooded people have one positive gene and one negative gene. If both positive parents pass on their negative gene, they can have a child with a negative blood type.
No, the child's blood group would be the same as one of it's parents.
No, it can't happen. if one of the parents or both are +, the child will be Positive. I don't know if 2 negatives can have a positive. But i do know that if one of the parents is positive and the other is negative, you can have a either a positive or negative child. (I have twins, one is negative and the other is positive.)
It is possible as the Rhesus factor is a dominant trait. So, even if the parents have only one allele for the factor, there is a 1/4th chance that the child could get neither allele from the parents and end up as O negative.
Yes, the child can be his. Further testing with DNA would be required to prove this, though. Blood typing alone cannot confirm this; the blood types mentioned do not exclude the possibility. The child can inherit B from the mother, so the child can be type B even if the father is type O. If the mother is Rh positive, she may only have one Rh+ gene, in which case she can have an Rh negative child. This does not factor into the dispute, however, as both father and child are Rh negative.
If both parents are B- they can only have children who are B- and O-. One would have to be positive in order to have a child with positive blood.
