No. If both parents are Rh negative, they are homozygous recessive for the Rh factor and can only pass on recessive alleles to their children, and a positive Rh factor is a dominant trait.
Yes
I'll wait for you to ask the question. Positive parents can have a negative baby as positive is dominant so they may both have one positive and one negative gene and the baby gets the two negative genes.
No, it is not possible.
not chance,but rarely can be.
A baby can be any blood type that is possible through the combination of the parents' genetic material. In this case, the baby could be blood type B positive like the parents, or it could be blood type O positive if both parents are carriers of the O blood type gene.
If the first baby has blood group O negative, it means that both parents must have passed on an O gene and a negative Rh factor gene to the baby. Therefore, the parents could have blood groups A, B, AB, or O with negative Rh factor.
If both parents have Type B blood the only blood type the child can have is either B or O not looking at whether one of the parents is negative or not.
a negative times a negative is a positive so the answer is positive
it it possible if someone from either parents' family has had it or haves it because of genes
no, he has at least one - but the other half could be + or - if baby is -- then both parents gave - meaning they both are one of these +- or --
No, if both parents are O negative (meaning they do not have the Rh antigen), they cannot have a Rh positive baby. RH positive blood type requires the presence of the Rh antigen when processing blood types.
Yes, it is possible for a mother with A positive blood and a father with O positive blood to have a baby with A negative blood. The baby would inherit one A allele from the mother and one O allele from the father, resulting in A negative blood type.
