Question

What happens during meiosis?a) Chromosome pairs separate to form new sex cells, increasing genetic variation.b) Each sex cell copies itself to form four new sex cells that are all identicalc) Each sex cell loses half of its chromosomes, decreasing genetic variationd) Chromosome pairs remain together when new sex cells are formed, maintaining the same level of genetic variation

Answer 1

Meiosis is a reductional division, which involves two rounds of division and results in four haploid cells.

During meiosis I, the homologous chromosomes pair and recombine, and after that, they are separated into two haploid cells.

During meiosis II, the sister chromatids are separated, and a total of four haploid cells are produced.

Of the options, the sentence that better describes what happens in meiosis is A, chromosome pairs separate to form new sex cells, increasing genetic variation.
