Show all of your work for the cross. What is this type of cross called? Incomplete dominance: Genes code for the production of specific proteins, many of which are enzymes. Different alleles at a locus code for alternative forms of a protein that differ in structure and when the protein is an enzyme, often have different degrees of catalytic activity. Therefore, a heterozygote genotvpe produces an intermediate phenotype.97 Assume that the trihybrid cross MM SS tt X mm ss TT is made in a plant species in which Mand S are dom- inant but there is no dominance between T and t.
