The two distinct divisions of meiosis are meiosis I and meiosis II. Meiosis I is responsible for genetic diversity, while meiosis II reduces the amount of DNA in the daughter cells. At the end of meiosis II, each daughter cell has 23 chromosomes.Know More
Meiosis I and meiosis II both have four stages: prophase, metaphase, anaphase and telophase. During prophase I, DNA condenses and the nuclear envelope disappears, making the chromosomes visible as tetrads. Genetic recombination occurs during prophase I and metaphase I, but it ends as soon as the tetrads pull apart in anaphase I. During telophase I, a nuclear envelope forms around the chromosomes with two chromatids, forming haploid nuclei.
In prophase II, the chromosomes with two chromatids begin to condense, forming a spindle. The chromosomes split during anaphase II, leaving each chromosome with only one chromatid. In telophase II, nuclear envelopes form around the chromosomes with single chromatids. The result of meiosis II is four haploid daughter cells.Learn more about Cells
The function of meiosis is for sexual reproduction as meiosis creates new cells for an organism. Meiosis has two cell divisions known as meiosis I and meiosis II.Full Answer >
During meiosis 1, a diploid cell's chromosomes segregate and produce four haploid cells. It is the completion of this phase that leads to genetic diversity.Full Answer >
Meiosis is a cell division process that occurs twice to produce four haploid daughter cells, according to Biology4Kids. Meiosis I occurs first and creates two daughter cells, and then meiosis II begins and creates two more daughter cells.Full Answer >
Arizona State University states that meiosis is how sexually reproducing organisms, including humans, produce gametes, or sex cells. Gametes are fundamentally different from the body, or somatic, cells of sexually reproductive organisms because gametes only have half of the genetic code in their nucleus. When two different gametes fuse and produce a zygote, their half-complements of genetic material combine to form a complete genome with the full complement of chromosomes.Full Answer >
