Genes establish a potential of expression, and environment determines where a person's phenotype will fall.This boundary of genetic influence is referred to as __________.

Question

Quizplus · Accepted Answer

The boundary of genetic influence is known as the reaction range, which refers to the potential or range of phenotypic outcomes that can occur due to genetic variation in combination with environmental influences. This means that genes set limits on what is possible, but the specific expression of traits depends on environmental factors. Option A, environmental influence, is incorrect because it does not specifically refer to the genetic boundary. Option B, gene boundaries, is not a commonly used term in genetics. Option C, heritability estimate, refers to the proportion of variation in a trait that can be attributed to genetic factors, but it does not specifically refer to the boundary of genetic influence on phenotype.
