The Coat Color of Calico Cats is a Result of ________

Question

The coat color of calico cats is a result of ________.
A) maternal inheritance
B) X-inactivation
C) imprinting
D) extranuclear inheritance

Accepted Answer

The coat color of calico cats is a result of X-inactivation, which is a process by which one of the two X chromosomes in female mammals is randomly inactivated in each cell during early embryonic development. This results in patches of different coat colors, including white, black, and orange, on the cat's fur. Maternal inheritance, imprinting, and extranuclear inheritance do not play a significant role in determining the coat color of calico cats.
