In humans, the amount of DNA in a somatic cell is about 40 - 50 pg (pico grams). One pg is 10-15 grams.
i don't know for certain but i don't think theres a limit to DNA but do you mean chromosomes? and that's different for lots of species
humans have 23 pairs of chromosomes
Who knows, there could be thousands of them in retrospect. But after meiosis it's just maybe a couple for a single genome.
23 types of sperm will be produced by meiosis when it is completed.

Mitosis was the norm until Meiosis (two sexes) evolved 580 Million Years Ago. Each Cell produced has exactly half of the information of each of the Cells it came from, meaning, each Cell has half of the characteristics its "parent" had.
They do not differ much. The proteins in each are slightly different.
during meiosis (i believe), its not transcription i know that much
It is not exact.It is almost fifty percent.
Meiosis produces cells with half of the DNA of a normal cell so that when two cells that have gone through meiosis (like sperm and egg) are joined, the cell formed has the normal amount of DNA. If meiosis didn't happen each new organism would have twice as much DNA as it's parents.
First of all, most cells in the body divide through the process of mitosis, except for sex cells, sperm and eggs. They must divide through a different process, meiosis, because they must end up with half the number of chromosomes as a typical cell after they divide. Another word for a cell with half the normal amount of chromosomes is a haploid cell. Diploid cells are cells with the normal amount of chromosomes. Meiosis occurs much more often in men, who are constantly reproducing sperm, whereas women are born with all the eggs they will ever have. Cells go through meiosis whenever they are in need of creating more haploid sex cells.
variationvarietyMeiosis introduces genetic variation. Mitosis produces daughter cells that are identical to the parent cell. However, meiosis produces offspring with half the genetic material from each parent - and therefore much more diversity.
If meiosis did not occur then the chromosome number would double each generation, and the cell could not survive with this increasingly larger number of chromosomes.
There are four haploid cells because your supposed to have 48 chromosomes but the first cell has 4 times as much so it needs to divide 4 times.Hope this helps.

It would be wrong to consider mitosis insignificant as it helps in cell repair and replacement in our daily life and it would be impossible to survive without it and asexual reproduction as well but if it weren't for meiosis, none of us would have been born :) Meiosis is responsible for the division for our gamete cells which leads to the formation a zygote. from there on mitosis takes over.
Meiosis is a type of cell division which results in four daughter cells containing half the number of chromosomes of the parent cell. In the human life cycle, meiosis immediately precedes fertilization
