Answer 2

The correct answer is:

а) Мейоз – это способ образования половых клеток

The process of meiosis is responsible for the formation of gametes (sex cells) in organisms. It involves two rounds of cell division, resulting in the production of four haploid cells. Meiosis is essential for sexual reproduction and ensures genetic diversity in offspring.

Explanation:

Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It involves two rounds of division, known as meiosis I and meiosis II, resulting in the production of four haploid cells (gametes). These gametes have half the number of chromosomes as the parent cell.

During meiosis I, homologous chromosomes pair up and exchange genetic material through a process called crossing over. This genetic recombination contributes to genetic diversity. The paired chromosomes then separate, reducing the chromosome number by half.

Meiosis II is similar to mitosis, where the sister chromatids of each chromosome separate, resulting in the formation of four haploid cells.

The terms "reductional division" and "equational division" are used to describe the two rounds of meiotic division. Meiosis I is referred to as the reductional division because it reduces the chromosome number by half. Meiosis II is called the equational division because it separates the sister chromatids without further reducing the chromosome number.
