Cold Spring Harbor, New York—An unusual gene called callipyge, or “beautiful buttocks,” causes sheep to add muscle in their hindquarters. New work presented at the genome meeting shows that this gene has an unusual, non-Mendelian pattern of inheritance, and understanding its expression may one day help explain non-Mendelian patterns in human genetic diseases.
