Question

В отличие от митоза мейоз: а) завершается образованием четырех гаплоидних клеток; б) завершается образованием двух диплоидних клеток; в) состоит из одного деления; г) состоит из двух последовательных делений

Answer 1

Мейоз - это деление клеток при котором образуются половые клетки ( с гаплоидным -одинарным набором хромосом) для мейоза --- ответ-- а,г

Митоз деление соматических клеток (с диплоидным набором хромосом - двойным) -- б,в

Answer 2

Difference Between Meiosis and Mitosis

Meiosis and mitosis are both processes of cell division, but they have distinct differences. Let's explore the differences between meiosis and mitosis based on the given options:

a) Meiosis concludes with the formation of four haploid cells. - Meiosis indeed concludes with the formation of four haploid cells. During meiosis, a single round of DNA replication is followed by two rounds of cell division, resulting in four daughter cells, each with half the number of chromosomes as the original parent cell. - Source: "Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell" .

b) Mitosis concludes with the formation of two diploid cells. - This statement is incorrect. Mitosis concludes with the formation of two identical diploid cells. During mitosis, a single cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell. - Source: "Mitosis is a process where a single cell divides into two identical daughter cells (cell division) with the same number of chromosomes as the parent cell" .

c) Meiosis consists of one division. - This statement is incorrect. Meiosis consists of two consecutive divisions: meiosis I and meiosis II. Each division includes prophase, metaphase, anaphase, and telophase stages. - Source: "Meiosis consists of two consecutive cell divisions, namely meiosis I and meiosis II" .

d) Meiosis consists of two consecutive divisions. - This statement is correct. Meiosis consists of two consecutive divisions: meiosis I and meiosis II. Each division includes prophase, metaphase, anaphase, and telophase stages. - Source: "Meiosis consists of two consecutive cell divisions, namely meiosis I and meiosis II" .

In summary, the correct statements are: - Meiosis concludes with the formation of four haploid cells. - Mitosis concludes with the formation of two diploid cells. - Meiosis consists of two consecutive divisions.
