How much time takes the completion of meiosis 1 and 2?
The duration of meiosis can vary significantly depending on the organism and the specific cell type. In humans, meiosis 1 can take several hours to complete, while meiosis 2 is generally faster, often taking less than an hour. However, the entire meiotic process, including prophase stages and interphase, can span days to weeks in some organisms. Overall, the timing is highly variable across species and cell types.
When a cell divides how much of the cytoplasm does each new cell get?
about half
What is the importance of meiosis in living things?
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.
How does the cell membrane differ from the cell?
They do not differ much. The proteins in each are slightly different.
Random separation of chromosomes during anaphase?
During anaphase, chromosomes are randomly separated due to the attachment of spindle fibers to the centromeres of each chromosome. The pulling force exerted by the spindle fibers on the centromeres causes the chromosomes to move towards opposite poles of the cell. This random separation ensures that each daughter cell receives a complete and unique set of chromosomes.
Why must cells undergo meiosis before they can fuse together to produce another organism?
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.
When does a cell go through meiosis?
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.
How much DNA would a gamete contain if the DNA was also replicated between meiosis you and meiosis ii?
A gamete would contain the haploid amount of DNA, which is one complete set of genetic material. During meiosis, DNA is replicated once during S phase but is not copied again between meiosis I and meiosis II, so each gamete ends up with a single set of chromosomes.
How many nuclei are present when meiosis 2 is complete?
After meiosis II there will be four cells, each with its own genetically unique haploid nucleus. In females, only one of the four cells becomes a gamete (ovum). The ovum receives the majority of cytoplasm during cytokinesis, and is much larger than the other cells. In males, all four cells will become gametes (sperm cells).
What will happen if meiosis did not occur in sexually reproducing organisms?
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.
When a cell divides how much of the cytoplasm does each new cell get?
about half
What does meiosis introduce into the daughter cells that Mitosis does not?
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.
How many mature eggs does each complete meiotic division yield?
1 mature egg. The remaining 3 cells produced by meiosis are non-functional and are called polar bodies. They are much smaller than the egg, i.e. the egg took all or their cytoplasm during the divisions
How much chromosomes does each cell have?
46

Why does meiosis result in more genetic variation than mitosis?
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.
How many haploid cells are made during meiosis?
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.
