RH Macy's parents were American Quakers living on Nantucket Island in the state of Massachusetts.
We are looking for the possible Rh blood types of a baby.Parental information:Mother Rh pos -- can be (++) or (+-) = contributes (+) or (-) geneFather Rh pos -- can be (++) or (+-) = contributes (+) or (-) geneBaby receives one gene from each parent: Baby is Rh (++) = Rh posBaby is Rh (+-) = Rh posBaby is Rh (--) = Rh negTherefore, depending on the exact genetics of the parents, the baby may be Rh positive or negative.
Yes, for a child to be Rh negative, both parents must carry at least one Rh negative allele. If both parents are Rh positive, they can still have an Rh negative child if both are carriers of the Rh negative allele.
Yes, this can happen, if the alleles are Hetero for both parents (Rh+Rh-) heterozygous.
Theoretically :This is rare actually, and there is two possible genotypes1-Both parents are positive but with different alleles ( heterozygous )---> Rh+Rh- vs Rh+Rh-here there is 25% of kids may have Rh-Rh-2-Both parents are positive with same alleles ( homozygous )---> Rh+Rh+ vs Rh+Rh+here there is Zero% of kids to be negative, because all will be positive.Medical Answers need confirmation and re-confirmation.
Can a child with RH neg blood come from parents that are A positive and A negative
That is always possible if both the parents are heterozygous for Rh antigen gene. It means that both the parents. There are 2 different alleles for the Rh factor known as Rh+ and Rh-.Someone who is "Rh positive" or "Rh+" has at least one Rh+ allele, but could have two. Their genotype could be either Rh+/Rh+ or Rh+/Rh-. Someone who Rh- has a genotype of Rh-/Rh-. If their genotypes are Rh+/Rh-, then their is possibility of of Rh- also.Rh factorPossible genotypesRh+Rh+/Rh+Rh+/Rh-Rh-Rh-/Rh-Prof. A.L. Bhatiahttp://www.competition-india.blogspot.com/http://www.albhatia.inType O blood is also recessive to type A, so both parents could be heterozygous type A's. Their genotypes would have to be A/O.
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 like when : * his father is AA RH- and his mother is OO RH- he will be AO RH- (A-). * his father is AO RH- and his mother is OO RH- he may be: # AO RH- (A-) # OO RH- (O-) So, the most one is ( A-) . So, ( A- ) child may get from: # A- and O- # A- and B- # AB- and AB- # ect .....
Each person carries two bits of rh imformation, called alleles, and each can be positive or negative. A person is rh+ if they have at least one positive allele. Only if both their alleles are negative are they considered as rh-. When two parents have a baby, they each pass one allele on. So if both parent has one positive and one negative allele, and both passed on their negative allele to their baby, then the baby would be rh negative. The chances of two rh positive parents having a rh negative baby are about 18%.
If both parents are Rh positive, the baby has about a 93% chance of being Rh positive as well. However, without knowing the genotype of the parents (i.e., whether they are homozygous or heterozygous for the Rh factor), it is not possible to predict the baby's Rh status with certainty.
Yes
Yes, it is possible for parents and their children to have different Rh factors. Each parent contributes one Rh factor gene, which can result in children having a different Rh factor than their parents.
