B) polygenic inheritance
C) single gene effect
D) none of these

Question

Quizplus · Accepted Answer

Traits that occur as a continuum in a population are likely to be due to polygenic inheritance, which means they are controlled by multiple genes. X-linked disorders are caused by genes found on the X chromosome and typically affect one sex more than the other. Single gene effects are caused by mutations in a single gene and usually result in distinct phenotypes rather than a continuous range of variation. Therefore, options A and C are not the best choices.
