Assume that for a given gene a mutation creates an allele that functions as a dominant negative. The gene codes for a protein that forms a trimer (3 subunits are needed) within the cell. If at least one of the subunits has the mutant structure the entire protein is inactivated. For a heterozygous individual (one dominant negative allele and one wild-type allele in the same individual), what percent of the trimer present in the cell will be active
