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. This condition is controlled by a sex-linked gene and it is recessive. Now,  suppose that the herd bull (the dominant one which does most of the breeding) who is  normal (XN) mates with a cow that is a carrier for rabbit hock.  What are his chances of producing a normal son (bull)? If he mates with this cow every year, what percentage of their daughters will have normal knees? What percentage of their daughters
