Which of the following processes generates a continuum (spectrum)of varying phenotypes?
A) Pleiotropy
B) Polygenic inheritance
C) Epistasis
D) Single-gene traits

Question

Quizplus · Accepted Answer

Polygenic inheritance is the process by which a trait is controlled by multiple genes, each with small effects, leading to a range of phenotypes that form a continuum. Examples include height, skin color, and eye color. Pleiotropy refers to a single gene affecting multiple traits, while epistasis is the interaction between genes affecting a trait. Single-gene traits show distinct phenotypes, not a continuum.
