Question

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

the correct answer is option d

Step-by-step solution

Step 1. Inroduction

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

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.

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.
