Trivia Quiz On Codominance And Incomplete Dominance!

An allele is one of the possible forms of a gene, and they can either completely blend with each other completely and form new phenotype or not blend together completely. This trivia quiz is on codominance and incomplete dominance and is designed to walk you through the two processes and how they occur in the human body.
