A or O positive or negative
No. If both parents are positive, the child will be positive. If both parents are negative, the child will be negative. Parents who are negative and positive can have children who are either positive or negative. '+' + '+' = '+' '-' + '-' = '-' '+' + '-' = '-' or '+'
Yes, if both parents are AO genotype there is a 25% chance of the parents producing a type O child. Since both parents are Rh positive the probability of an Rh positive child in at least 75%.
if both parents have positive o blood their child must have positive o blood
Yes, one or even both of his parents can be A positive.
No. If both parents are type O, the child will be O. If both are A, the child can be either A or O. If both are B, the child can be either B or O. If both are AB, the child can be A, B, or AB (but not O).
yes because you either get your parent's traits, the opposite traits, or a little of both but because both parents are positive the child could be positive OR negative
Yes, if both parents have the genotype AO, then the child can have the O from both parents, phenotype O
yes
No. If both parents are type O, the child will also be type O.
If they both have type A blood, they cannot have a child type B.
yes
yes it is possoble, each child is different and the parents blood type determains the child's. but both children will have a positive no matter what because both parents have positive.
