Explanation: <u>Convergent</u> evolution occurs when organisms share a trait that originated in an ancestor but changed over time in different populations.
Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations.
