Becker muscular dystrophy is due to a mutation in the same gene that causes the more severe Duchenne muscular dystrophy. This is an X linked recessive condition that causes muscular weakness that begins and a later age and progresses more slowly than Duchenne muscular dystrophy which is often lethal by age 20. One of my former students had a father who had this condition. She did not have the condition. If she has three sons with a male who does not have the condition, what is the chance that all of her sons would have the condition? 100% 3/4 1/2 1/4 1/8 3/8
