What else can I help you with?
Is it possible for one pair of parents to have some Rh positive children and some Rh negative children?
Yes, this can happen, if the alleles are Hetero for both parents (Rh+Rh-) heterozygous.
Can a man with O rh plus and a woman with O rh plus have a child with O rh- blood?
Yes - it is possible. Firstly, if both parents have the blood type O, then the child must also have blood type O. Rh positive is dominant, so a person who is Rh + may be heterozygous (Rh+/Rh-). Both parents in this case would need to be heterozygous for the child to be Rh-.
Can a child w a- blood type have a father with a plus and a mother w O plus?
Yes A is dominant over O so if a child inherited the A gene from the father the child would be A Plus (or Rh +) is dominant over Negative (or Rh -). So if mother and father are both heterozygous for the Rh gene then 1 in 4 children will be Negative
Can o positive and o positive make a B negative or b positive?
No - if both parents have blood type O, then the only possibility for their children is also blood type O. If they are both heterozygous for Rh (+/-) then they could have either + or - children. If either of them are homozygous (Rh+Rh+) then all the children will be +.
What happens if a woman is heterozygous Rh positive and her child's father is hemozygous Rh negative?
There is a 50% that offspring will be Rh negative.
If you are rh negative and 3 of your 4 children are rh negative and more than 50 of your grandchildren are rh negative what is the probability of you coming from parents that are both rh positive?
i know im rh neg and my 2 brothers are rh neg. So i guess we ar eok. i have 3 children myself, but i dont know their blood type.
Can a baby be born with positive blood if both parents are negative?
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.
If a mother has a blood type a plus and the father has the blood type a- can the offspring have o negative blood?
Yes....if both parents are carriers of type "O" then they have a 25% chance of having a child with type "O" blood type (O is a recessive trait). The child would have to receive the recessive "O" from both parents. Regarding the Rh factor. If mom is a carrier of the negative Rh factor, then there is a 50% chance that the offspring may carry the Rh negative factor. Hope this helps...
Is it more common to be Rh plus or Rh?
Rh plus
Can parents both blood type B plus have a chlid with A- blood type?
No, it can't happen. none of the parents have the allele to make a kid with A blood type, and they can have Rh- child if both parent rh alleles are heterozygous.
Can a mother O positive and a father rh negative have O negative child?
Yes, this is possible. only if the mother's alleles are Heterozygous (Rh+Rh-).
What happens when b positive woman marry a o negative man?
The blood type of any children would depend on the zygosity in the woman. (Both O and Rh negative are recessive, and will be homozygous in the man). If the woman is homozygous B, then the children will B. If the woman is heterozygous B, either O or B (with 50% chance of each). In the same way, if the woman is homozygous Rh positive, then the children will also be positive. If the woman is heterozygous, then children will be either positive or negative. In short, the possibilities for child blood types are either B or O, with Rh positive or negative.
