Front

What is complete dominance?

Back

A genetic scenario where one allele completely masks the effect of another allele.

Front

What is codominance?

Back

Front

What is incomplete dominance?

Back

A genetic scenario where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.
