If the father is O positive and the mother is A negative what would the child's blood type be?
This depends on whether the father is carrying the Rh-negative
blood type allele and whether the mother is carrying the O allele,
because these are both recessive. The child could be any of the
You read a lot of stuff on an rh negative mother and rh positive father but what if it is the opposite with an rh positive mother and rh negative father?
Can a mother with a negative blood and father with o positive blood have b positive blood group baby?
What is the genotype o a man with type A negative blood whose father was B positive and whose mother was AB positive?
Discounting rare but possible mutations the following holds true. Parents blood groups A and A, A and B, A and O, B and B, B and O, O and O can produce type O blood in their children. The rhesus factor (Rhesus positive/rhesus negative) depends on the rhesus pairing in the parents as follows: Father rhesus positive, mother rhesus positive or rhesus negative = rhesus positive or rhesus negative Father rhesus negative, mother rhesus positive…
If the father is from type O positive and the mother from group type B positive can the children if they are twins have one B negative and the other O negative?
What are the possible blood types of a father if the offspring is A positive and the mother is O positive?
Yes, both O and rh negative traits are recessive. The father is recessive for both traits. The O negative mother however, can be either homozygous dominant (positive) for rh, producing a rh positive baby. If the mother was heterozygous, having an allele for both positive an negative rh antigen, has a 50-50 chance producing an O positive child.
