Meiosis reduces the number of chromosome sets from two (diploid), to one (haploid). In mitosis the daughter cells are genetically identical to the parent cell, but meiosis produces cells that differ genetically from the parent cell as well as each other. In the final stage of meiosis II there end up being 4n daughter cells. So remember mitosis is diploid and meiosis is haploid.

What are the end results of mitosis and meiosis?
1) Mitosis occurs in body cells and produces two diploid (2n) daughter cells that are genetically identical for growth and repair. Meiosis occurs in the gonads and produces four haploid (n) daughter cells that are genetically unique for reproduction. 2) Meiosis requires two cycles to halve the chromosome number.. The first cell division of meiosis called meiosis I is similar to mitosis.. The second cell division halves the chromosome number from 2n to n.. This is required to produce gametes (cells with n number of chromosomes - sperm or ova) so that when the gametes join together during fertilization they produce a zygote that is 2n. 3) Crossing over during meiosis increases the genetic variation of the gametes and thus the next generation.. Crossing over occurs in prophase I of meiosis when homologous chromosomes pair up in tetrads and non-sister chromatids swap pieces of DNA.. This creates unique chromosomes.. Variation is also increased by the independent assortment of chromosomes during meiosis (a gamete can receive the paternal chromosome or maternal chromosome for each chromosome) and random fertilization (any sperm can fertilize any egg)..

What stage of meiosis is the chromosome number reduced?
In Anaphase I
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)
How do the chromosomes get to the stage of meiosis prophase?
A nucleus is signals the rest of the cell that the cell is ready to undergo meiosis, in which case the chromosomes begin to condense with the help of histones, which is the beginning of prophase I of meiosis.
How do the products of meiosis compare to the original cell think about chromosome number?
No, they have half the number.
How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
What is Meiosis definition?
Meiosis is the type of cell division that results in gametes (sex cells) that possess half the chromosome number of the parent cell. In other words, meiosis reduces the chromosome number by one-half.
Change in chromosome number in mitosis and meiosis?
Meiosis results in a change in chromosome number indicated by division of cells into two identical cells. This is a process that is used for purposes of reproduction.
In what type of cell division does the chromosome number reduce by one half and gametes form?
Meiosis produces gametes which have half the number of chromosomes that other cells of the body have.
How does mitosis differ from meiosis in terms of chromosome segregation?
Meiosis results in four cells, each with half the chromosomes of the original cell. Mitosis results in two cells, each which has the same number of chromosomes as the original cell.
What happens to the chromosomes number by the end of meiosis?
The chromosome number at the end of meiosis is half of the parent cell
What decrease cellular chromosome number by half is?
Meiosis.
How is the chromosome number affected by cell division?
In Mitosis, the chromosome number remains the same. In meiosis, the number of chromosomes is halved.

During meiosis the chromosome number does what?
During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.
What does the chromosome number do during meiosis?
During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.
What are the definition and stages of meiosis?
There are 12 stages of meiosis. Meiosis is a type of cell that is dived, which reduces the chromosome number by half.
