QUESTION

Phenotype reflects genotype more precisely when heritability is?

OPTIONS

(A) Low
(B) High
(C) Medium
(D) All of the above

ANSWER

(B) High

EXPLANATION

Phenotypic performance reflects genetic differences more accurately when heritability is high because a larger proportion of phenotypic variance is attributable to genetic variance. With low heritability, environmental effects make phenotype a poorer indicator of genotype; 'medium' does not provide the strongest relationship.
