No. O and Rh negative are both recessive traits--both alleles must be that trait before it expresses. The term for an A positive child from two O negative parents is "grounds for divorce."
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.)
Yes. A negative Rh factor is recessive. Everyone has 2 copies of this gene (one from mom, one from dad.) Since positive is dominant and negative is recessive, if you have one of each (heterozygous), you will have a positive blood Rh, but sitll carry the gene for negative Rh. If this is the case for both parents, then the child has a 25% chance of being Rh negative.

Nope
Negatives and Positives Positive + Positive = Positive Negative + Negative = Positive Negative + Positive = Negative Positive + Negative = Negative
Yes, two Rh negatives can have a positive baby if both parents are carriers of the Rhesus D gene. In this case, both parents will pass on recessive genes (Rh negative) but at least one parent must also possess the RhD gene in order for their child to be born Rh positive. please investigate before answering questions
A Negative plus a positive = a negative because negative and a positive cannot work together Negative + Negative= Positive Positive + Positive = Positive when your dealing with numbers such as : -2 + 2 would equal a negative 4 -2 +-2 would equal a positive 4
Theoretically :This is rare actually, and there is two possible genotypes1-Both parents are positive but with different alleles ( heterozygous )---> Rh+Rh- vs Rh+Rh-here there is 25% of kids may have Rh-Rh-2-Both parents are positive with same alleles ( homozygous )---> Rh+Rh+ vs Rh+Rh+here there is Zero% of kids to be negative, because all will be positive.Medical Answers need confirmation and re-confirmation.
negative*negative=positive ex. negative 2*negative 2= positive 4
positive + positive = add (e.g. 2 + 1 = 3)positive + negative = take (e.g. 2 + -1 = 2 - 1 = 1)positive - positive = take (e.g. 2 - 1 = 1)positive - negative = add (e.g. 2 - -1 = 2 + 1 = 3)negative + positive = add (e.g. -2 + 1 = -1)negative + negative = take (e.g. -2 + -1 = -2 - 1 = -3)negative - positive = take (e.g. -2 - 1 = -3)negative - negative = add (e.g. -2 - -1 = -2 + 1 = -1)
yes, for the blood types there are 2 genes that decide ABO/+- the ABO is based on a gene with 3 genotypes, which are i, IA and IB if a person has ii, they have O blood, if they have iIA or IAIA they have A blood, if they have iIB or IBIB they have B blood and if they have IAIB they have AB blood positibe/negative is the rhesusfactor, it actually works with 3 genes(C, D, and E), but anything other than cde/cde will give rhesus-positive blood, so a parent with ii-cde/cde will have O-negative, and iIA/CDe/CDe will give A-positive, the only 2 blood-types the children can have with this set of parents are A-positive and O-positive
Negative times negative is positive. Negative 2 times negative 2 equals positive 4.
