Answer:
EARLY ANAPHASE
Explanation:
A cleavage furrow is a division which occurs in a cell's surface before cell division. It begins with cell's “pinching” its cell membrane and cytoplasm down the middle resulting in formation of two daughter cells.
Animal cell cleavage furrow is as a result of a ring of actin microfilaments known as the contractile ring, formed during EARLY ANAPHASE. The resultant bridge is divided and rearranged to yield two identical daughter cells when cytokinesis is occurring.
