Incomplete Dominance in Traits and Disease

Incomplete dominance is a pattern of inheritance where two alleles both affect a trait in a heterozygous organism. In this case, one allele is not fully dominant over the other. The result is a phenotype that looks like a blend or intermediate form.

Mendel performed thousands of cross-breeding experiments. In one of his most famous experiments, the monohybrid cross, he described the two versions, or alleles, of a single gene. One of these alleles was dominant, while the other was recessive.

In this example, with purple and white pea flowers, only the dominant purple allele appears in...
