Assume That a Mutation Occurs in the Gene Responsible for the Production

True/False

Assume that a mutation occurs in the gene responsible for the production of hexosaminidase A, such that only about 50 percent of the enzyme activity is found in the heterozygote compared with a homozygous normal individual. If heterozygotes are
phenotypically normal, we would say that the mutant allele is recessive to its normal allele.
