Asked by Sydney

Suppose a dominant gene for a particular disease is found on the X chromosome and is denoted as X^D. The mother is X^D X^D and the father is XY. What percent of the couple's children will show the disease?

I understand how it works if the X^D gene was recessive, but because it is dominant, do the males also show the disease?

All the children will receive the dominant X^D from mommy. What does that tell you?
