Question

what happens to chromosome number as a result of meiosis?
a it is halved.
b it stays the same.
c it is doubled.
d it is tripled.

Explanation:

Meiosis is a type of cell division that produces gametes (sperm and egg cells). In meiosis, the parent cell (diploid, with 2n chromosomes) undergoes two rounds of division. The first division separates homologous chromosomes, and the second separates sister chromatids. As a result, the four daughter cells produced have half the number of chromosomes of the parent cell (haploid, with n chromosomes). So the chromosome number is halved. Option A states this, while B (stays same, like in mitosis), C (doubled, not in meiosis), and D (tripled, not a result of meiosis) are incorrect.

Answer:

A. It is halved.
