How many chromosomes are present in a mosquito cell at each what stages Meiosis?
A mosquito cell has 6 chromosomes in total. During meiosis, the cell goes through two rounds of division. In meiosis I, the cell reduces its chromosome number to half (3 chromosomes) and in meiosis II, it divides again to produce four daughter cells, each with 3 chromosomes.
What happens during synapsas in meiosis?
The purpose of synapsis in meiosis is to increase genetic variability. It does this as the homolog pairs match up, which means there are 4 chromosomes of like, but possibly unique, DNA data in the grouping. This allows the cell. as it proceeds through Anaphase 1 and Anaphase 2 to separate the individual chromosomes first into 2 pairs then as individuals, which inturn adds to the variability as 1 chromosome goes to each daughter cell. .
What is the role of meiosis to sexual reproduction?
Meiosis produces daughter cells with half the genetic material of normal cells. This means that when the gametes from each parent meet, the resulting offspring will once again have the correct number of chromosomes. Meiosis allows half of the chromosomes come from each parent - which is vital for sexual reproduction.
When do we have 46 chromosomes in meiosis or mitosis?
we have 46 chromosomes in Mitosis during interphase when the DNA doubles, but really Humans have 23 chromosomes. Meiosis is reproduction and goes through Mitosis twice but skips interphase the second time and creates gametes(sex cells) -Marina20
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.
How many phases meiosis goes through?
Meiosis goes through two main phases: meiosis I and meiosis II. Meiosis I involves homologous chromosomes separating, resulting in two daughter cells with half the original number of chromosomes. Meiosis II involves sister chromatids separating, resulting in four haploid daughter cells.

What is atypical meiosis?
It is when something goes worng in the seperating of chromosomes.
Why does meiosis require two cellular divisions?
Meiosis is divided into Meiosis I and Meiosis II because the initial cell divides twice producing four genetically different sex cells (gametes) Each time a cell divides, it goes through Prophase, Metaphase, Anaphase, and Telophase. See the link below for a diagram showing the process.
What happens when something goes wrong during meiosis - -?
it can go really weird
How are sex cells produced and how many chromosomes are present at each stage?
Starts as a germ cell- 46 chromosomes Goes through phase 1 meiosis- 2 daughter cells each 46 chromosomes Goes through phase 2 meiosis- chromosomes are sorted randomly and recombined (crossing over)- gametes (sex cells) 23 chromosomes
Strictly speaking mitosis and meiosis are divisions of the?
Mitosis is division of a cell. Consists of the stages Prophase, Metaphase, Anaphase, and Telaphase. Mitosis is part of the cell cycle. Meiosis is the division of a sex cell. Such as sperm or egg. Meiosis is unique because it goes through the stages twice. Prophase I, Prophase II, Metaphase I, and Metaphase II, etc.

Why is meiosis sometimes called reduction division?
Due to the fact that meiosis consists of two "phases" or cycles and goes from a diploid state (2n) to a haploid state (n) it is often times referred to as reduction division. This is because the parent cell starts off with two sets of chromosomes and the daughter cells only end up with one set of chromosomes when the entire process is complete.
How are chromosomes in a cell at metaphase of mitosis similar to and different from the chromosomes in a cell at metaphase of meiosis 2?
Mitosis refers to the division of cells , so it goes from haploid to diploid (increases). Meiosis on the other hand refers to the division of gametes (sexual reproductive cell such as an egg or sperm), so it goes from diploid to haploid (decreases). Since meiosis, has an e just remember this one refers to the sexual reproduction of cells. Mitosis creates 2 identical cells and meiosis creates 4 different cells (each one contain half of the original content). Meiosis involves in sexual reproduction whereas mitosis involves in asexual reproduction.
What kinds of cells are produces from meiosis?
Meiosis is a special kind of cell division that produces haploid (1n) cells. During meiosis, a single cell goes through two cell divisions (meiosis I and meiosis II.) Meiosis takes place only in the reproductive tissues of an organism.
