gene x can exist as a normal allele and also as a dominant mutant allele that causes a disease. you purify protein x from a homozygous normal individual and also from an individual that is homozygous for the mutant allele. you have an assay to determine the function of protein x. when you assay 1 mg of the purified protein from a normal homozygote, the activity is 100%. when you mix together 0.5 mg of the normal protein and 0.5 mg of the mutant protein, the activity is 13%. based on this experiment, why type of dominant mutant is this?
