2.2: Multiple alleles, incomplete dominance, and codominance

WebThe incomplete dominance model of inher-itance suggests that the interaction that occurs between two different alleles results in a hybrid with an appearance somewhere between the phenotypes of the two parental varieties. The codom-inance model of inheritance is similar to the incomplete dominance model, but in the codominance WebIncomplete dominance and codominance are both types of inheritance where one allele (a form of a gene) isn’t completely dominant over the other allele.
