Question

Cleft palate is ____.
A) controlled only by genetics
B) a continuously distributed trait
C) controlled by a single gene pair
D) only transmitted from father to son
E) explained by the threshold model of complex traits

Accepted Answer

Cleft palate is best explained by the threshold model of complex traits, which suggests that multiple genes and environmental factors contribute to its occurrence. It is not solely controlled by genetics, a single gene pair, or transmitted only from father to son, and it does not represent a continuously distributed trait in the traditional sense.
