2. 

In the meiotic cell divison in daughter cells are produced by two successive division in which

[A]. first division is equational, second is reductional
[B]. first division is reductional and second is equational
[C]. both divisions are reductional
[D]. both divisions are equational

Answer: Option A

Explanation:

No answer description available for this question.

Meiotic division is reducing division of cell so how first division is equational?

Md. Abdullah. said: (Apr 27, 2017)  
I think the correct answer is B. Because the number of chromosome is halfed in meiosis I and in meiosis II only mitosis like cell division occur.

Maninder said: (Nov 6, 2017)  
Answer is correct because in 1st division chromosomes doubles and hence they are diploid but in second division they divide and become haploid.

Asit said: (Jan 21, 2018)  
Answer is B, because the homologous chromosomes are separated at anaphase 1.

Riya Basu said: (Jun 16, 2019)  
First division is reductional as homologous chromosomes are separated in anaphase 1 (so if there are suppose 8 chromosomes i.e., 4 pair of homologous chromosomes then each daughter cell receives 4 each thereby reducing the chromosome number) whereas the second one is equational as sister chromatids are separated in anaphase 2 and each of the chromatids now behave as chromosome of daughter cell thereby chromosome number remain unchanged i.e., 4.
