Question

question 11
the sex chromosome complement of a normal human female is

1. xo
2. xx
3. xy
4. yy

Explanation:

In humans, the sex - determining system is based on the presence of X and Y chromosomes. Females have two X chromosomes. The XO condition is seen in some disorders (like Turner syndrome in humans, but it's not the normal female complement). XY is the normal male complement, and YY is not a normal human complement as humans have one pair of sex chromosomes (either XX or XY).

Answer:

1. XX
