What else can I help you with?
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 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.
Does an Rh negative child require both parents carry at least one Rh negative allele?
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.
If both parents are rhesus positive can they have a negative baby?
Yes, if both parents each have the dominant positive AND recessive negative genes, they have a 1 in 4 chance of having a child with rh-neg blood. Both mother and father would have to pass the recessive gene to the offspring.
Can a child born with rh negative blood type be the offspring of an o positive father?
It depends on the genotype of the Rh+ parent. If that person is heterozygous, then yes there is a 50% chance of an Rh- baby.Father's Group (negative)Mother's Group (positive heterozygous)Rh +Rh -Rh -Rh +, Rh -Rh -, Rh -Rh -Rh +, Rh -Rh - Rh -http://www.bloodbook.com/inherited.htmlIf the positive parent is homozygous, the baby will be positive:Father's Group (negative)Mother's Group (positive homozygous)Rh +Rh +Rh -Rh +, Rh -Rh +, Rh -Rh -Rh +, Rh -Rh + Rh -
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
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.
Can 2 Rh parents have a Rh- child?
No, it can't happen. if one of the parents or both are +, the child will be Positive. I don't know if 2 negatives can have a positive. But i do know that if one of the parents is positive and the other is negative, you can have a either a positive or negative child. (I have twins, one is negative and the other is positive.)
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.
Does an Rh negative child require both parents carry at least one Rh negative allele?
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.
Can an a positive parent and an O negative parent have an A negative child?
No. If both parents are Rh+, they can only pass on Rh+.
Can an A positive parent and an O positive parent have an A negative child?
No. If both parents are Rh+, they can only pass on Rh+.
Can a positive parents have o negative child?
No, it can't happen. if one of the parents or both are +, the child will be Positive. I don't know if 2 negatives can have a positive. But i do know that if one of the parents is positive and the other is negative, you can have a either a positive or negative child. (I have twins, one is negative and the other is positive.)
