Answer to Question 1

ANS: D
Because hemophilia is caused by a mutation of the X chromosome, all female children of a man with hemophilia are carriers of the disorder and can transmit the mutated gene to their offspring. Sons of a man with hemophilia will not have the disorder. Hemophilia is caused by a single genetic mutation and is not a multifactorial inherited condition.

Answer to Question 2

ANS: B
When one parent has an autosomal recessive disorder and the other parent has no genes for the autosomal recessive disorder, the children will not display characteristics of the disorder. However, the children will be carriers of the autosomal recessive disorder.
