Answer to Question 1

ANS: C
Type O individuals have both anti-A and anti-B antibodies but not O.

Answer to Question 2

Odds dictate that children will share one haplotype with half their siblings and either no haplo-types or both haplotypes with a quarter of their siblings. Thus, the chance of finding a match among siblings is much higher (25) than the general population.
