Front

What is incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a phenotype that is a blend of the two alleles.

What does the term 'phenotype' refer to?

Back

Back

Genotype refers to the genetic constitution of an organism, while phenotype refers to the observable traits.
