(a) Rh X rh 



(b) rh X R'r 



(c) /2V0 X R'R' 



(d) Rh^ X R'R"

11. From the point of view of the offspring, is it more or less desirable 

 for an R-negative man to marry an R-positive woman than it is for an 

 R-positive man to marry an R-negative woman? Explain. 



12. Provided there is no agglutination because of the A-B or M-N 

 blood groups, is there any objection if: blood from an R4- woman is 

 injected into an RH- woman; blood from an RH- woman is injected into 

 an R — woman; blood from an R— woman is injected into an R+ woman? 

 Would it matter in any of these cases if the R— woman had had a child 

 by an R-j- man?
