In a heterozygous pair of alleles, the phenotype reflects one allele more than the other. This is referred to as a(n) _____.
A) additive pattern
B) multifactorial pattern
C) dominant-recessive pattern
D) polygenic pattern

Question

Quizplus · Accepted Answer

In a dominant-recessive pattern, one allele (dominant) masks the expression of the other allele (recessive) in a heterozygous pair. Therefore, the phenotype reflects the dominant allele more than the recessive allele. The other answer choices (additive pattern, multifactorial pattern, and polygenic pattern) do not specifically refer to the pattern of expression of alleles in a heterozygous pair.

In a Heterozygous Pair of Alleles, the Phenotype Reflects One
