Negative is recessive...you can have a negative also.
Yes, the baby can be O+, it should be noted though if the mother also carries the trait for a negative Rh factor the baby clould also be O-.
yes
yes
It takes two rh negative parents to produce an rh negative baby.
Yes
Yes, Rh negative is recessive, if your mother has two positive allelles, you have one of each and are rh positive. If your mother is heterozygous (negative and positive alleles) You have a 50% chance getting a positive allele.
It's possible if both parents are heterozygous for both Rh factor and ... type-A-ness, whatever the word for that is. That is if they're both +- and AO genetically, they'd both have blood type A positive, but they'd both have the potential to pass along blood type O and Rh factor negative. If the baby gets O- from both mom and dad, then the baby would be OO -- and therefore O negative.It's not necessarily what you would expect (7 times out of 8, the baby would be type A, Rh postive, or both), but it is possible.If they have a B negative baby, mom's been fooling around on dad.
There are no compatibility issues with the ABO gene and the production of offspring. There might be an issue if the mother is Rh negative and the father is Rh positive with the resulting baby inheriting the Rh positive gene.
If a dad is O+ and the mom is B+, there is no reason for the baby to be born unhealthy, at least due to blood typing.
YES. Blood type is determined by two alleles. An "A" individual can be homozygous "AA" or heterozygous "AO" and still be considered type A. The same is true of a "B" individual. If the father is "AO" and the mother is "BO" then statistically, they have a 25% chance of having a child that is "OO" or type O.
Yes, if the father's genotype is AO, and both of them have +- genotype. However, this would be very rare.
Yes. And I am A neg. Dad is O pos and mom A pos
