Question

which of the following traits are mendelian, and which show more complex patterns of inheritance? body size in humans coat color in labrador dogs yellow versus green pea color in pea plants intelligence in humans

Explanation:

Mendelian traits follow simple dominant - recessive inheritance patterns. Body size in humans is polygenic and influenced by environment, so complex. Coat color in Labrador dogs has multiple gene interactions, complex. Yellow versus green pea color in pea plants follows Mendel's laws, Mendelian. Human intelligence is polygenic and influenced by environment, complex.

Answer:

body size in humans: complex
coat color in Labrador dogs: complex
yellow versus green pea color in pea plants: Mendelian
intelligence in humans: complex
