These divisions are broadly classified into two categories which are: “Mitosis” and “Meiosis” the former is called the equational division while the latter is called reductional division.

Daughter cells have half the # of chromosomes as parent cell. 46. STUDY. Anaphase II 8. A haploid cell contains one full set of chromosomes. B. Meiosis is the process of chromosomal reduction in eukaryotic cells (plants, animals, and fungi), which leads to the production of germ cells (gametes/sex cells) needed for sexual reproduction. In meiosis, a double set of chromosomes (diploid) is reduced to a single set of chromosomes (haploid) to produce germ cells or spores.

Enyong Lumanlan. SUMMARY: Meiosis vs. Mitosis mitosis one DNA replication (back in S phase of interphase) one division results in two genetically identical daughter cells homologous chromosomes do not pair do not cross-over do not segregate meiosis one DNA replication (back in S phase of interphase) two divisions (reductive division) results in up to four genetically • Cell division that reduces the homologous chromosome number by one-half. The last part of the Cell Cycle is called Mitosis and has 4 phases during which the cell divides into 2 cells Prophase The Cell begins the division process. Meiosis is a form of cell division in which one diploid (2n) cell produces four haploid (n) cells or gametes. Two divisions (meiosis I and meiosis II). Essential Standard: Bio 1.1 Understand the relationship between the structures and functions of cells and their organelles. Answer key to meiosis worksheet where students practice naming the phases of meiosis. It is the division of diploid germ cells that reduces the chromosome number by half forming haploid daughter cells (gametes). Cell Division –Meiosis – the process in which the number of chromosomes in the original cell is . * Meiosis II Second division of meiosis: Gamete formation Prophase 2: DNA does not replicate in interphase 2. MEIOSIS II Only one homolog of each chromosome is present in the cell. This is a Powerpoint for Cells Division which is found in Topic 1: Cell Biology of GCSE Biology and Double Science. (All 4 daughter cells are haploid.) Bio 1.2 Analyze the cell as a living system. As in mitotic division, meiosis I is preceded by replication of the DNA content of the dividing cell. ...
