Chapter 10, Problem 9WIO
Summary Introduction
To explain:
“Would the dominant X linked illness to affect women as often as men”.
Concept introduction:
The X linked disorder means that the genes causing the disorder or disease is present on the X chromosomes. The X linked disorder can be dominant or recessive. If the father carries the affected X chromosome, it will pass the affected chromosomes to all daughters not to son. If the mother carries the affected X chromosomes, it will pass the affected chromosomes to all the progeny.

Students have asked these similar questions
If a father is affected by an X-linked
dominant condition and the mother is
normal, what is the probability of their
children being affected?
All sons will be affected.
Half of the sons will be affected.
All daughters will be affected.
Half of the daughters will be carriers.
Why are males affected by X-linked disorders much more oftenthan females?
Can a woman who is affected by an X-linked dominant disorder have a child who is not affected? Why or why not?
