Assertion: During zygotene, chromosmes show bivalent stage.
Reason: Bivalent is half the number of chromosomes

A

B

If both Assertion `&` Reason are True but Reason is not correct explanation of the Assertion.

C

If Assertion is Trie but the Reason is False.

D

If both Assertion `&` Reason are false

The correct Answer is:
b
During zygotene, because of the paring of the homologous, the nucleus contains half the number of chromosmes. Each unit is a bivalent composed of two homologous chromosomers.
