Why does meiosis require two cellular divisions?

Answer 1

Meiosis is divided into Meiosis I and Meiosis II because the initial cell divides twice producing four genetically

different sex cells (gametes) Each time a cell divides, it goes through Prophase, Metaphase, Anaphase,

and Telophase.

See the link below for a diagram showing the process.

Answer 2

Meiosis is divided into Meiosis I and Meiosis II because a cell goes through two cell divisions in Meiosis. The purpose of Meiosis 1 is to separate homologous chromosomes, whereas the purpose of Meiosis II is to separate sister chromatids. The two are considered phases of Meiosis (as opposed to phases of the cell cycle as a whole) because there is no gap between Meiosis 1 and Meiosis 2; A cell that goes through Meiosis I will immediately go through Meiosis II.

Answer 3

in meiosis-I, the number of chromosomes of the daughter cell is halved the number that of the mother. so, in meiosis1 the chromosome number is halved. in order to restore the uniform number the daughter cells undergoes meiosis-II which is similar to mitosis, and thus it maintains the same chromosome number

Answer 4

because two divisions are necessary to ensure the correct number of chromosomes (23 individual chromosomes which have the ability to fuse with the opposite gamete to result in 23 PAIRS of chromosomes assuming no mutations)

Answer 5

Meiosis I separates homologous chromosomes. Meiosis II separates sister chromatids.

Answer 6

It happens because Lal Pekin is a pro @ violin. Also that is because Lol loves Moe. I hope this answer your question,

LOL

Answer 7

Meiosis is a double division because the chromosomes that make up the tetrads separate during meiosis I. Then, during meiosis II, the chromatids separate.

Answer 8

Because your mum was in the way.
