Human height is an example of
A.polygenic inheritance
B.a single-gene trait
C.epistasis
D.sex linkage
Explanation
Core Concept
Human height is influenced by many genes and by environmental factors, so phenotype varies continuously across a population rather than falling into a few simple Mendelian classes. When many small effects combine, the distribution can be approximately bell-shaped, but polygenic inheritance does not guarantee a perfect normal distribution.
Correct Answer
Apolygenic inheritance
