Which of the following describes a situation where two different alleles are both fully expressed in a heterozygous individual, beyond Mendel's simple dominance?

• Codominance

• Incomplete dominance

• Epistasis

• Polygenic inheritance

What is the term for a single trait controlled by multiple genes, which Mendel's laws do not account for?

• Polygenic inheritance

• Monogenic inheritance

• Epistasis

• Codominance

Which genetic phenomenon can result in offspring with a phenotype that is not a blend of the parents, but rather a new trait, beyond Mendel's laws?
