What is the probability that a carrier and a person who has a -linked genetic disorder will have a son with

seems it would be 50/50 to 25/75. draw it out... the carrier has 1 of the gene, the one who has the gene would have 2... You have to draw out the square and put the 1's in each box... a 1 for the carrier, and 2 1's in the square. Pretty much, the offspring of these 2 people would have the disorder.
