Question
Chapter 10.6, Problem 1MC
Summary Introduction
To explain:
How incomplete dominance and codominance increases the number of
Concept introduction:
Incomplete dominance produces a fine mixture or blend of the expressions of the two dominant and recessive alleles, in the phenotype of an individual. Codominance occurs when both the recessive and dominant alleles expresses themselves independently in the phenotype of an individual.
