No, if the male was O pos, the female was O neg, and the baby was O pos, then the mother might need a Rhogam shot. A rhogam shot prevents a "neg" mom from developing antibodies to her "pos" baby which could cause a miscarriage. It's really no big deal, just a little shot.
No
possibility not
If a person has the Rh factor, then they are positive. If they don't have the Rh factor, they are negative. The Rh factor is dominant, so a mother with it would have an Rh positive baby even if the father is negative for the Rh factor.
Yes. The father's phenotype is AO+*; the mother's is OO--.
No they can not. two positives do not make a negative
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.
Negative is recessive...you can have a negative also.
Yes, Rh negative is recessive, if your mother has two positive allelles, you have one of each and are rh positive. If your mother is heterozygous (negative and positive alleles) You have a 50% chance getting a positive allele.
Yes.
No. They can have an O positive, an O negative, A B positive, or a B negative child.
can an o positive and an o negative make an a positive baby
If mother is heterozygote yes.
yes its possible
B positive or negative or, O positive or negative.
