During early development, the Y chromosome produces a substance called "testis determining factor" (TDF)that causes the indifferent gonad to become a testis. This would be an example of
A) capacitation.
B) activation.
C) differentiation.
D) induction.
E) predilection.

Question

Quizplus · Accepted Answer

The process described in the question is an example of induction, where a signal from one group of cells (in this case, the Y chromosome) causes neighboring cells to differentiate into a specific cell type (in this case, a testis). Capacitation refers to the process by which sperm become capable of fertilizing an egg, activation typically refers to the initiation of a cellular process, and predilection is not a scientific term commonly used in this context. Differentiation involves cells becoming specialized into specific types, but the question specifically refers to the mechanism by which this occurs (induction by TDF).
