Question

Hemophilia is a sex-linked, recessive trait. Which of the following describes the probability of hemophilia in the offspring of a man who does not have hemophilia and a woman whose father is a hemophiliac?
Group of answer choices


Each of their sons will have hemophilia
None of their daughters will have hemophilia
Their sons have a 25% chance of having hemophilia
There is a 50% chance that their daughters will have hemophilia

Answer 1

Either none or 25%,

If the mother and father don’t have hemophilia, but the grandpa does, it’s a slight chance because it’s not the child’s actual bloodline
