Question

what happens to the number of chromosomes during meiosis? it increases. it doubles. it decreases. it remains the same.

Explanation:

Meiosis is a type of cell division that results in the formation of gametes (sex cells). In meiosis, the parent cell undergoes two rounds of division (meiosis I and meiosis II). The key event in meiosis I is homologous chromosome separation. This reduces the chromosome number from diploid (2n, two sets of chromosomes) to haploid (n, one set of chromosomes). For example, in human cells, the diploid number is 46. After meiosis I, the chromosome number is reduced to 23. Meiosis II is similar to mitosis (a type of cell division for growth and repair where chromosome number remains the same), but it starts with haploid cells. So overall, the chromosome number decreases during meiosis.

Answer:

It decreases.
