The interaction of a heterozygous pair of alleles in such a way that the phenotype reflects one allele more than the other is referred to as a(n) :

A) additive pattern.
B) multifactorial pattern.
C) dominant–recessive pattern.
D) polygenic pattern.

Heterozygous

A genetic condition where an individual has two different alleles of a gene.

Dominant–Recessive Pattern

The interaction of a heterozygous pair of alleles in such a way that the phenotype reflects one allele (the dominant gene) more than the other (the recessive gene).

Additive Pattern

A situation or process where the effects of separate factors combine in a straightforward, cumulative manner.
