QUESTION
Permanent genetic correlation between the traits is due to?
OPTIONS
(A) Linkage
(B) Pleiotropy
(C) Heterozygosity
(D) Homozygosity
ANSWER
(B) Pleiotropy
EXPLANATION
A permanent genetic correlation between traits is primarily attributable to pleiotropy, in which one gene or set of genes influences more than one trait. Linkage can contribute to genetic association, particularly over shorter evolutionary or breeding timescales, but pleiotropy provides the stable genetic basis intended by the question.
