The amount of enzyme activity in a cell that is homozygous for a mutant allele is 400 units. The amount of enzyme activity in a cell homozygous for the WT allele is 200 units. The amount of enzyme activity in a heterozygote is 300 units. What is the dominance relationship between the WT and mutant allele for the phenotype of amount of enzyme per cell?
◦ The WT allele is dominant.
◦ The mutant allele is dominant.
◦ The WT and mutant alleles are codominant.
◦ The WT and mutant alleles show incomplete dominance.
◦ It is impossible to determine from the information given.
