What is the pattern of inheritance for polygenic trait?
A
Mendelian inheritance pattern
B
Non-mendelian inheritance pattern
C
Autosomal dominant pattern
D
X-linked recessive inheritance pattern
Explanation
Polygenic inheritance shows continuous phenotypic variation and follows a non-Mendelian inheritance pattern.
Detailed Solution
Polygenic traits are controlled by three or more genes with cumulative additive effects showing continuous bell-shaped phenotypic variation (e.g. human skin colour, height), deviating from typical Mendelian monogenic ratios, hence following a non-Mendelian inheritance pattern.
