Meiosis was discovered and described for the first time in sea urchin eggs in 1876 by the German biologist Oscar Hertwig. It was described again in 1883, at the level of chromosomes, by the Belgian zoologist Edouard Van Beneden, in Ascarisworms' eggs.
A total of four daughter cells are created during meiosis. There are two phases of meiosis, meiosis 1 and meiosis 2. During meiosis 1 two daughter cells are created while during meiosis 2 four daughter cells are created.
The two main stages of meiosis are meiosis I and meiosis II. Meiosis I involves the separation of homologous chromosomes, while meiosis II involves the separation of sister chromatids. Each stage includes prophase, metaphase, anaphase, and telophase.
Yes, there is no replication step between meiosis I and meiosis II. The DNA remains in a duplicated state from the end of meiosis I and goes directly into meiosis II, where the sister chromatids are separated.
Meiosis II is identical to Mitosis. Meiosis is split into two stages, Meiosis I and Meiosis II. Meiosis I is similar to mitosis however the cells resulting from it have half as many chromosomes as the parent cell.
The products of meiosis 1 are two haploid daughter cells with duplicated chromosomes, while the products of meiosis 2 are four haploid daughter cells with unduplicated chromosomes. Meiosis 1 separates homologous chromosomes, while meiosis 2 separates sister chromatids.

Meiosis was discovered in 1876 by the German biologist Oscar Hertwig. He observed the process of meiosis while studying sea urchin eggs under a microscope.
Meiosis was discovered by German biologist Oscar Hertwig in 1876 while studying sea urchin eggs.
Thomas Hunt Morgan discovered most of what we know today, but meiosis has always existed.
Meiosis was discovered as a distinct process from mitosis by German biologist Oscar Hertwig in 1876. Hertwig observed the unique division of sex cells during his research on fertilization and reproduction in organisms, leading to the identification of meiosis as the specialized cell division for gamete formation.
Meiosis I and meiosis II
If you mean meiosis I and meiosis II, then no they are not identical, but meiosis II does follow meiosis I.
The two types of meiosis are meiosis I and meiosis II. Meiosis I involves homologous chromosomes separating, while meiosis II involves sister chromatids separating.
Meiosis 1 and Meiosis 2
Meiosis I & Meiosis II
Meiosis does in fact divide twice, once in meiosis I (cytokinesis) and meiosis II (cytokinesis) basically it divides into four daughter cells at the end of meiosis. Two from meiosis I and four in meiosis II
Meiosis 1 and Meiosis 2
