Biology Question: Possible blood types of offspring.
What if the mother is type O+ and the father is A-? What would the offspring's blood type be? The offspring could be: (a) A+, or O+ (b) A-, or O- (c) A+, A-, O+, or O- (d) A+, or O-
If the mother of a child is blood type O+ and the child is A-, what blood type would the father be? Does the Rh factor of the child being - (negative) mean that one of the parents has to be negative? Both the parents are Rh - all of the siblings are Rh-as well. Could two Rh- parents give birth to a Rh+ child? and visa versa? ...continues
