Question

what happens to homologous chromosomes during meiosis​

Answer 1

☆$\small\green {\sf{Answer }}$☆

Thus, in mitosis, homologous chromosomes (generally) do not line up, nor do we see crossing over (recombination) occurring. These events are what we see happening in meiosis, which produces haploid cells (e.g., sperm and ova). Mitosis is all about conserving the chromosomal number.

Answer 2

$\huge{\underline{\underline{\sf{Answer:-}}}}$

⠀

Meiosis. ... Homologous chromosomes separate during the first meiotic division and the resulting sister chromatids separate during the second division. At the end of meiosis, four distinct daughter cells are produced. Each of these is haploid and contains only half of the chromosomes of the original cell.
