Assertion: Meiotic division results in the production of haploid cells.
Reason: Synapsis occurs during zygotene of meiosis.

Options

A. Both assertion and reason are true and the reason is a correct explanation of assertion.
B. Both assertion and reaso are true, but the reason is not the correct explanation of the assertion.
C. Assertion is true, but reason is false
D. Assertion is false, but reason is true

Answer

B

Explanation

Meiotic division is a reductional division. It occurs in reproductive cells and maintains the fixed number of chromosomes in sexually reproducing organisms. Prophase-I of meiotic division is a long phase, which is divided into five subphases, i.e., leptotene, zygotene, pachytene, diplotene and diakinesis.
In zygotene phase, homologous chromosomes pair up, this process is called synapsis. each pair is called a bivalent.
