Question

Select the correct option:

Identify the given figures showing meiotic phases and select the correct option.

• A. A - Metaphase, B - Anaphase, C - Telophase
• B. A - Metaphase I, B - Anaphase I, C - Telophase I
• C. A - Metaphase II, B - Anaphase II, C - Telophase II
• D. A - Anaphase I, B -Metaphase I, C - Telophase I

Answer 1

Answer: (B)

A - Metaphase I, B - Anaphase I, C - Telophase I

All the stages are of the meiosis 1 because here we can see the bivalent or tetrad stages. Metaphase is the stage where chromosome comes on the equator and bivalent arrange themselves on the equatorial plate. Then anaphase 1 involves the separation of a homologous chromosome which start moving up to opposite poles and each tetrad is divided into two daughter cells. So anaphase involves the production of chromosome number and is also known as disjunction. Telophase 1 shows the formation of two daughter nuclei but the chromosome number is half then the chromosome number of mother cell and nuclear membrane reappears.

So, the correct option is 'A - Metaphase I, B - Anaphase I, C - Telophase I'
