Question
Chapter 13, Problem 1A
Summary Introduction
Introduction:
The genes, which are carried on the both of the sex chromosomes, are called sex-linked genes. The sex-linked genes not only determine the sex of an individual, they also affect some of the sex-linked traits.

a. XH Y
b. XHXh
c. XhXh
d. Xh Y
In order for a male to inherit a sex-linked (X-linked) disorder, he must receive the allele from: a. his mother only. b. either his mother or father. c. his father only. d. both his mother and father.
