and and one from their father, which get passed from generation to generation.... all babies get genes from their parents, who in turn got genes from their parents... -all- of your genes came from your parents, if your parents don't have the gene, you can't get it. (unless you're a mutant)

Hair and skin color are complicated because there are lots of different genes that control it, which is why we have so many shades of colors of hair and skin color. But the Rh factor is simple, just two options + or -. If you are Rh-, then you are - - (one negative came from mom and one from dad). If you are Rh+, then you are either + + or + - (it only takes one positive to make you positive)

If both parents are Rh+ and have mixed genes (+ -), then it is possible that each of them will give the - gene to their child, making the child Rh- (- -). (there is a 25% chance that the child will be Rh- and 75% chance that the child will get a positive from either one or both parents)

If one parent is Rh+ and has 2 positive genes (+ +) then it doesn't matter what the other parent is, all the children will be Rh+ Here is another website that may be able to help ans some quest: http://www.thetech.org/genetics/ask.php?id=114

So, to answer your question. Two Rh+ parents can have an Rh- child..... but the negative still came from the parents.

Can parents with AB positive and A negative blood have a baby with 0 negative blood?

Yes


When Parents with b positive and o positive blood have baby with o negative blood group?

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.


Can a baby be born with positive blood if both parents have negative blood?

No, it is not possible.


Can two parents with A positive blood have an Rh A negative baby?

not chance,but rarely can be.


What blood type can a baby be if the father and mother are both type B positive?

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.


What are parents blood group with their first baby is of blood group o negative?

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.


What will two negative parents have positive or negative baby?

a negative times a negative is a positive so the answer is positive


How can a baby have b negative blood when both parents are b positive?

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.


If a mother has a positive blood and father has o positive blood can the baby have ab negative blood?

it it possible if someone from either parents' family has had it or haves it because of genes


If you have A positive blood and your baby has O negative blood does that mean the father of your child would have to have negative blood?

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 --


Can a mother with A positive blood and father with O positive blood have a baby with A negative blood?

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.


Can a O negative parent and an RH O negative parent make a positive baby?

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.
