Question

if a colour-blind male marries a female carrier of colour-blind, what is the probability of the couple getting a colour-blind son?

Answer 1

There is 100% that the offspring will be colorblind

Answer 2

1/16 because it is a 1/2 chance their child is a son 1/2 they have a daughter another 1/2 chance if their son is color blind and another 1/2 they have a color blind daughter. I hope this helps :) 1/2 * 1/2 * 1/2 * 1/2 = 1/16
