Segregation of Mendelian factors (no lin...

Segregation of Mendelian factors (no linkage no crossing over) occurs during:

A

anaphase-I

B

anaphase-II

C

diplotene

D

metaphase-I

Text Solution

Verified by Experts

The correct Answer is:
A
At the end of anaphase-I, two groups of chromosomes (one at each pole) are produced. Each such group is having half the original number of chromosomes present in the parent nucleus. So, anaphase-I results in the reduction of chromosome number to half and segregation of Mendelian factors.
