Yes, if both the father and mother have the genotype of AO, then they would both show up as phenotype A and they could have a child with type O blood. As O is recessive, the type A would be dominant and therefore show up as the blood type. The mother could contribute the positive Rh factor leading to type O+ in the child.
Yes, it is possible for both mother and father to be RH positive and a child to be RH negative.
Yes.
No. The mother must be either AO or AA, and the father OO. No combination of these can give rise to an AB child. However, a negative mother and a positive father can have a negative child, by rhesus factors, if the father has genotype +-.
Mother is a plus child 0 plus what could father be?
Yes A is dominant over O so if a child inherited the A gene from the father the child would be A Plus (or Rh +) is dominant over Negative (or Rh -). So if mother and father are both heterozygous for the Rh gene then 1 in 4 children will be Negative
mother could be either B or AB and she could also be Negative or Positive.
No
no
A
No!
The child can have either Rh positive or Rh negative blood. More information is needed on the mother's genotype to know for sure. With the information currently given, the child has a 25% chance of being Rh negative.
A+
