Comparison of individual and collaborative answers of justify/explain quiz

Question Incorrect answer after first quiz Answer after collaborative quiz
Mary is pregnant with her second child. Mary is Rh negative. During the pregnancy the fetus develops erythroblastosis fetalis where the red blood cells (RBC) are destroyed by the mother's antibodies to the Rh factor. Both babies have the same father. Is he Rh+, Rh−, or neither? Explain your answer Rh−: b/c when the mother and father both have the same Rh factors they can not coexist with each other and that causes problems Rh+: baby gets from mother's body; reject the Rh+ because she is Rh−
Rh−: because the baby is Rh− and mother is trouble producing Rh− RBC Rh+: b/c he caused the baby to have Rh+ blood
Rh+: b/c it is the same father and the mother is Rh− Rh+: because during the (first) baby, the body started producing antibodies but not long enough to destroy the baby
Rh+: the gene carried by the male Rh+: b/c mother is Rh− and baby is Rh+
The father is Rh− b/c Mary was positive so they change that the baby had came from the father Rh+: b/c she is Rh−
Rh−: b/c the baby is Rh+; does not have · · · Rh+: because of dominance
The father is Rh+ but more dominant No change
Rh+: not exactly sure why No change
Neither, he doesn't affect the child No change
Rh+: gene needed to be placed in mother in order for erythroblastosis to occur in child No change
Rh+: if the second baby's DNA was rejected so to speak it means that the father's genes were dominant in the baby and he is Rh+ No change
