What are sex cells formed by meiosis with only half the chromosomes?
mitosis produces cells exactly identical to the parent. This means that they have all 46 chromosomes and are ready to function. In meiosis however, cells are formed with only 23 chromosomes (half of the usual 46) and are not ready to function on their own. Cells produced by meiosis are commonly referred to as sex cells. (egg and sperm) when the egg and sperm fuse together, it produces a new cell with the usual 46…
If a cell in a mosquito undergoes meiosis how many chromosomes will each resulting in a cell contain?
8 cells are formed and you were suppose to put one instead of meiosis you Meiosis one forms 2 cells, each having half the parental chromosomes, but each is doubled consisting of 2 chromatids. In Meiosis II, each cell produces 2 daughter cells, each having chromosomes formed by separation of chromatids were present in cells at end of Meiosis one. So that One cells after passing Meiosis one & II provides 4 haploid 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…
What is the process were it guarantees that the number of chromosomes in gametes is half the number of chromosomes in body cells?
Meiosis. Meiosis is the process in which gametes are produced. In meiosis, 4 haploid (think haploid- half) daughter cells are produced from the parent cell. These cells have half the number of chromosomes as the parent cell. For example, normal human cells have 46 chromosomes, where gametes have only 23.
Because meiosis is when the cells divide to form cells that have half of the original chromosome number, thus the number of chromosomes is reduced. For example a cell that has 6 chromosomes that divides by meiosis will produce only 3 chromosomes in each of the four daughter cells. Meiosis is refered to as reduction division because the number of chromosomes in the daughter cells has been reduced. Meiosis produces four daughter cells that have…
the similarities is that they both are the prossess of making cells. the difference is that mitosis makes regular cells with for humans 46 chromosomes, and meiosis is making reproductive cells which for humans have half the chromosomes so they have 23 chromosomes. how i remember this is that for meiosis it sounds like it's missing the T so its missing half the chromosomes.
Meiosis I: Prophase I - DNA is exchanged between homologous chromosomes Metaphase I - chromosomes meet in the centre of the nucleus Anaphase I - homologous chromosomes are pulled apart Telophase I - chromosomes arrive at the poles Cytokinesis - the cell membrane pinches together, and separate cells are formed. Meiosis II involves the same stages, but ends with 4 daughter cells which contain half the genetic material (known as germ cells).
How does the number of chromosomes in the two new cells compare with the numbers in the original cell at the end of the cell division?
How many chromosome are in the original cell compared to those in the new cells formed by cell division?
Meiosis occurs in sex cells because sex cells must end up with half the number of chromosomes as normal cells after division. Since mitosis produces 2 identical cells with the normal amount of chromosomes, a different process is needed in order to produce 4 genetically different cells with half the number of chromosomes as normal cells. This process is called meiosis.
As the result of meiosis, haploid cells are produced. These have half the number of chromosomes as the parent cells. When cells divide, DNA is copied so each daughter cell has the same number and type of chromosomes (a clone). When sex cells are produced, each cell has half the number. There are four of these sex cells in meiosis. In mitosis there are two cells.
