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 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.
Can a A positive blood type mother give birth to Rh negative daughter?
Can a child with RH neg blood come from parents that are A positive and A negative
Why do rh positive parents have an rh negative baby?
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%.
Can your father and mother have Rh positive factor and you be Rh negative?
YES. Maybe both of your parents are half-Rh positive, but not a full-blown Rh positive. Your parents will have 25% chances of getting a Rh negative offspring (Out of 4 children, only 1 become Rh negative) This comes true in our family. Both myself and my husband are Rh positive and our kid (3 years) is Rh negative. My blood group is B+ve, and my husband is A1B+ve and our kid is A1-ve.
Can the firstborn baby be Rh negative?
Yes, the firstborn baby can be Rh negative if both parents carry the Rh-negative gene. The Rh factor is inherited from the parents, and if the mother is Rh negative and the father is also Rh negative, their child will be Rh negative. However, if the mother is Rh positive and the father is Rh negative, the child can either be Rh positive or Rh negative depending on the specific alleles inherited.
If the parents are Rh positive could they produce an Rh negative child or just Rh positive offspring?
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.
Can parents have both B Rh positive and A1 Rh positive children?
Yes
Can parents that are both a negative have an ab positive child?
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
Can o positive and a positive parents have o negative child?
Yes. Since the Rh factor is recessive if both parents have a copy of the gene they can have an Rh negative child.
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 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 +.
