Chapter 11: Q. 4 (page 294)

At which stage of meiosis is sister chromatids separated from each other?

a. prophase I

b. prophase II

c. anaphase I

d. anaphase II

Short Answer

Expert verified

the correct answer is option d

Step by step solution

01

Step 1. Inroduction

Meiosis involves two successive cell division and produce four haploid daughter cells.

02

Step 2. The explanation for correct option

Option d is correct because during anaphase II the sister chromatids are separated from each other by kinetochore tubules and brought toward opposite poles.

03

Step 3. The explanation for the incorrect option

Option a is incorrect because during prophase I homologous chromosomes pair form synapses by coming together.

Option b is incorrect because during prophase II chromosomes condense and form new spindles.

Option c is incorrect because during anaphase I homologous pairs of chromosomes are separated and move towards opposite poles of the cell.
