When is the chromosomes number reduced from 46 to 23?
During the Prophase stage of Meiosis, rather than Mitosis, chromosomes are split from 46 to 23. Meiosis is the same basic process as Mitosis, yet is what occurs in gametes rather than other non-gamete cells.
Human cell have 46 chromosomes before mitosis how many do they have after mitosis?
After mitosis, the cells will still have 46 chromosomes.Immediately after mitosis and cytokinesis (cell division), the cell has 46 chromosomes that have one chromatid (this is in G1). During S phase, the DNA replicates itself, so that now the cell has 46 chromosomes that each have two chromatids (this is where the doubling comes in). After G2, the cell enters mitosis, and these chromosomes divide, so that each half of the cell has 46 chromatids (this is where the division of DNA comes in). When this mitotic cycle finishes, the cell again has 46 chromosomes that each consist of one chromatid.
How many chromosomes are present when meiosis is started?
In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.
If a cell with 40 chromosomes undergoes mitosis each of the daughter cells will have chromosomes.?
Meiosis results in gametes that have half the number of chromosomes of other cells. A gamete carries one of each pair of homologous chromosomes. Their are 46 chromosoes in Meiosis I and 23 in Meiosis II.
How many pairs of chromosomes after mitosis?
There are 46 chromosomes after mitosis. It stays the same from the beginning.

How many chromosomes will be found in each daughter cell after mitosis?
46 chromosomes will be found in a human daughter cell after mitosis, 23 chromosomes will be found after meiosis.
Are homologous chromosomes present in both mitosis and meiosis?
Yes, homologous chromosomes are present in both mitosis and meiosis. In mitosis, homologous chromosomes do not pair up, while in meiosis, homologous chromosomes pair up during prophase I.
Before mitosis or meiosis DNA coils into what?
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
How do the results of mitosis and meiosis differ?
the amount of chromosomes in a cell. meiosis is used in sexual reproduction and mitosis is just making more cells. chromosomes in a human after meiosis=24; mitosis=48.

How do chromosomes align differently in meiosis compared to mitosis?
In meiosis, chromosomes align in pairs during metaphase I, while in mitosis, chromosomes align individually during metaphase.
How many chromosomes will the resulting cells have in mitosis?
This depends both on the cell undergoing mitosis and the stage in mitosis which is currently underway. Humans have 46 chromosomes per cell, but in some stages of mitosis have 92. Dogs have 78 chromosomes, but at some stages of mitosis have 156.
If a cell with 40 chromosomes undergoes mitosis each of the daughter cells will have chromosomes.?

How many pairs of chromosomes after mitosis?
There are 46 chromosomes after mitosis. It stays the same from the beginning.
How is the chromosomes number halved during cell division: through mitosis or meiosis?
The chromosomes number is halved during cell division through meiosis, not mitosis.
