Question

the combination of alleles a person inherits (aabbcc, aabbcc, etc.) predicts a distinct phenotype. we call this type of inheritance:

• codominant.
• multifactorial.
• polygenic.
• dominant.
• recessive.

Explanation:

The question describes inheritance where multiple alleles (from multiple genes, as indicated by the multi-letter allele combinations like aabbcc, AabbCc) predict a phenotype. Polygenic inheritance involves multiple genes contributing to a trait, which matches the scenario. Codominant refers to both alleles being expressed, multifactorial includes environmental factors, dominant/recessive involve single gene dominance—none fit as well as polygenic.

Answer:

polygonic.
