Defects in the Short Stature Homeobox (SHOX) genes result in a wide range of phenotypic disorders. Some individuals have severe skeletal defects, called Leri-Weill dyschondrosteosis (LWD), and others have a milder defect, known as SHOX-related short stature. If both copies of an allele must be present for a normal phenotype and a defect in one copy of the allele is sufficient to cause a mutant phenotype, the allele is said to be _______.
