Question

Which of the following statements best describes the major difference between anaphase of mitosis and anaphase I of meiosis?

A. In anaphase I, homologous pairs are separated but sister chromatids stay joined together.
B. In anaphase I, sister chromatids are separated, forming a total of four haploid cells.

Answer 1

Answer;

A. In anaphase I, homologous pairs are separated but sister chromatids stay joined together.

Step-by-step explanation;

-Anaphase of mitosis is stage during during which each chromosome's sister chromatids separate and move to opposite poles of the cell. The stage before anaphase, metaphase, the chromosomes are pulled to the metaphase plate, in the middle of the cell.

-Anaphase I begins when the two chromosomes of each bivalent (tetrad) separate and start moving toward opposite poles of the cell as a result of the action of the spindle. The sister chromatids remain attached at their centromeres and move together toward the poles.

Answer 2

"In anaphase I, homologous pairs are separated but sister chromatids stay joined together" is the one option among all the choices given in the question that best describes the major difference between anaphase of mitosis and anaphase I of meiosis. The correct option among all the options given in the question is option "A".
