X linked genes

"Bent" is a dominant X-linked gene in mice. It results in a short, crooked tail. A recessive allele produces normal tails.

If a normal-tailed female is mated to a bent-tailed male, what are the chances of a male having a bent tail?

 The bison herd on Konza Prairie has begun to show a genetic defect. Some of the

males have a condition known as "rabbit hock" in which the knee of the back leg is

malformed slightly. Assume the genes controlling this trait are sex-linked and that

the "rabbit hock'" is recessive (r) not normal knee (R).

Now, suppose that the herd bull is normal and mates

with a cow (female) that is a carrier for rabbit hock. What are the chances that their son will be normal?
