What occurs during meiosis?
During Meiosis the chromosomes pairs separate and are distributed to two different cells. The resulting sex cells have only half as many chromosomes as the other cells in the organism......
Why do you need haloid cells?
Haploid cells are necessary for meiosis. When a cell goes through meiosis, it effectively ends with four daughter cells with half the number of chromosomes as the original cell. When two cells join, the resulting zygote will have the number of chromosomes as the original cell. Example. Human sperm and egg cells are produced through meiosis. Egg cells with 46 chromosomes produce 4 daughter cells, each containing 23 chromosomes (if you are familiar with meiosis, you understand how this happens). When joined with a sperm cell (which also contains 23 chromosomes), they produce a zygote which contains 46 chromosomes (which is the number of a regular person). If regular diploid cells, containing 46 chromosomes each, joined then the resulting zygote would have 96 chromosomes (46+46). The offspring of those individuals would have 192 chromosomes (96+96), and so on and so forth...That's why haploid cells are important.
Main stage of meiosis?
The main stage of meiosis is called the "reduction division" or "meiosis I." During this stage, homologous chromosomes pair up and exchange genetic information through a process called crossing over. They then separate, resulting in two cells with half the number of chromosomes as the original cell. Meiosis II then follows, where sister chromatids separate, resulting in four non-identical daughter cells.
When do homologous chromosomes separate into the daughter cells?
They are separated in Anaphase I of Meiosis I.
How many chromosomes are in the daughter cells are in mitosis?
The daughter cells formed by meiosis are haploid, meaning they have only one set of chromosomes. In humans, the haploid number of chromosomes is 23.
How many chromosomes are in the resulting cells after human meiosis?
23 chromosomes
Why is it important for cells resulting from meiosis to be haploid?
It important for cells resulting from meiosis to be haploid because, it prevents the number of chromosomes per generation from getting bigger.
What occurs during meiosis?
During Meiosis the chromosomes pairs separate and are distributed to two different cells. The resulting sex cells have only half as many chromosomes as the other cells in the organism......
Are the daughter cells resulting from meiosis the same as parent cells?
no they have half the number of chromosomes than their parent cells
If Eukaryote cell has 20 chrosomes and undergoes meiosis what is the resulting number of cells and chromosomes?
2 cells and twenty chromatids each (or twenty half-chromosomes each), but I'm not sure for the human sex cells (meiosis) if they are the same for all the other cells in the body (mitosis). If eukaryotic cell having 20 chromosomes undergoes meiosis four cells will be formed, each having 10 chromosomes. This happens because in meiosis I, pairing between homologous chromosomes takes place and each chromosome from this pair gets separated to the opposite pole resulting into reduction of chromosome by half their original number. From these two haploid cell of meiosis I, meiosis second further divides each of these two cells to two by mitosis. Thus, four cells with 10 chromosomes each are formed.
What is the organ system Meisosis accures in?
Reproductive system. Meiosis is the formation of gametes which unlike regular cells have 23 unpaired chromosomes compared to regular cells which have 23 paired chromosomes or 46 total chromosomes, in humans that is.
What is it called when cells are copied with half the number of chromosomes?
The resulting cell is said to be haploid.
What are the three outcomes of meiosis?
Three outcomes of meiosis: it reduces chromosomes to the haploid number, it provides genetic variation, and it ensures the correct distribution of chromosomes into the resulting cells.
Which cell division mitosis or meiosis has genetic variation and are not just identical cells?
Meiosis. Genetic variation is achieved by the random division of the chromosomes between the two daughter cells, and further recombination of specific genes between paired chromosomes before the division.

Meiosis II is similar to which process?
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.
If a cell in a dog undergoes meiosis and another cell undergoes mitosis how many chromosomes will each resulting cell contain?
Meiosis is usually reserved for cells used in sexual reproduction. They have half the number of chromosomes found in the organism's somatic cells. A mosquito has six chromosomes in its somatic cells, and therefore would have three in each gamete formed by meiosis.
