The heritable component of phenotypic variance is?
OPTIONS
(A) VA
(B) VD
(C) VE
(D) VD+VE
ANSWER
(A) VA

The additive genetic variance, VA, is the heritable component most directly associated with resemblance between relatives and response to selection. Dominance variance (VD) is non-additive genetic variance, environmental variance (VE) is non-genetic, and VD+VE excludes the additive component asked for.
