A person with A positive blood may be a carrier for O negative blood. If the other parent is also a carrier of those traits, the baby could be O negative.
it is very possible.although it is impossible to get that with the parents the parents still has genes from the grandparents and great gradparent and etc. the punnett square goes on far back toward the first human beings. so if your were related George Washington for instance, if no one after him has big ears, you would have about 0.00000762939453% chance of having big ears. it is very very very very very very VERY EXTREMELY unlikely but happens in rare occasions
We are looking for the possible blood types of a baby.
Parental information:
yes
Negative is recessive...you can have a negative also.
yes

Yes
It takes two rh negative parents to produce an rh negative baby.
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-.
o negative
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.
No, they cannot.
No, they cannot.
For blood types, you must consider the antigens and antibodies that are involved. epending on the presence or absense of these proteins, a person may have A, B, AB, or O blood. With pregnancy the chief concern is the Rh factor, which determines whether somebody is positive or negative. If mom is positive and da is positive, then the baby will be positive for the Rh factor, and there will be no complications. This same concept occurs for parents that are both negative for the Rh factor. If mmom is positive and dad is negative, then the dominant gene (positive) will be found in the baby and there will be no problems. However, if mom is negative and dad is positive, then the baby will attain a positive Rh factor and be inside the mom's (negative) body. Then, the om's body will produce antibodies to ward off the foreign blood of the baby, possibly killing it. As long as a doctor is informed of this, the mom can take shot periodically to prevent the production of such antibodies an keep the baby safe.
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.
