2n in cytoplasm refers to the diploid number of chromosomes in a cell. Diploid means that two sets of chromosomes are present in the cytoplasm. In humans the diploid number is 46 chromosomes. This means that in human cells the 2n in cytoplasm is 46. In other organisms the 2n in cytoplasm can vary. For example:
- In fruit flies the 2n in cytoplasm is 8.
- In nematodes the 2n in cytoplasm is 6.
- In wheat the 2n in cytoplasm is 42.
The 2n in cytoplasm can be used to distinguish between haploid and diploid organisms. Haploid organisms such as yeast have only a single set of chromosomes in the cytoplasm. Diploid organisms such as humans have two sets of chromosomes in the cytoplasm.

∙ 15y agoGenerally, in Biology, n refers to the amount of chromosome sets a specific organism may have, particularly in a cell at any one time. In a non-dividing human cell, 2n should be the amount of chromosomes present, one set of chromosomes from the mother, one from the father. In mitosis, 2n should occur after the end of cytokinesis, the division of the cells. Before this, there are four copies of a genome.

∙ 12y ago2N refers to a diploid cell or organism, in which two copies of each gene are present. Cells before and after mitosis are 2N, or diploid. Cells before meiosis are 2n, and following meiosis are 1n, or haploid.

(in humans it means they have 46 chromosomes)

Why does meiosis result 1N cells rather than 2N cells?
During meiosis chromosomes are segregated at Anaphase I stage , this results in reduction in number of chromosomes from 2N to 1N .
What does n and 2n means?
2N Refers to a diploid cell or organism, in which two copies of each gene are present. Cells before and after mitosis are 2N, or diploid. Cells before meiosis are 2n, and following meiosis are 1n, or haploid.
What cell process is used to make gametes?
Gametes are Haploid (N) - From a Diploid (2N) cell, a cell must go through meiosis - From another Haploid cell, mitosis must occur to produce another cell.
What would be the outcome of meiosis you if none of the homologous chromosomes separate at anaphase?
Each duplicated chromosomes would be pulled to one side or the other spindle poll, which is what happens in anaphase 1 of meiosis.
Why are two sets of faces during Meiosis but only one during mitosis?

Why do gametes have n numbers of chromosomes but not 2n?
Gametes are produced by the type of cell division called meiosis. During meiosis the number of chromosomes are halved. So if a cell starts off with 2n chromosomes and divides by meiosis the new cells will end up with n chromosomes.
What are two parts of cell division?
Mitosis and Cytokinesis
How many chromosomes are in a human cell before and after meiosis?
When meiosis begins at Gap 1 phase (G1) the cell of a human has 46 chromosomes or 2n.
Why does meiosis result 1N cells rather than 2N cells?
During meiosis chromosomes are segregated at Anaphase I stage , this results in reduction in number of chromosomes from 2N to 1N .
Which or these is true of meiosis n n n 2n 2n n 2n 2n?
Meiosis produces haploid gametes which have the ' n ' symbol.
Which type of cell division is used during the production of spores?
2n sporophyte produces spores by meiosis and the n gametophyte produces gametes by mitosis -Inquiry into Life - eleventh edition aka my high school honors biology book: page 178 i think its meiosis...
What is true of meiosis n to n n to 2n 2n to n or 2n to 2n?
it is 2n -n because in meiosis a diploid 2n becomes a haploid n.
What cell begins meiosis and mitosis?
The process of meiosis always begins with diploid cells. The chromosomes in the cells divide, so the result is four haploid cells.
What does n and 2n means?
2N Refers to a diploid cell or organism, in which two copies of each gene are present. Cells before and after mitosis are 2N, or diploid. Cells before meiosis are 2n, and following meiosis are 1n, or haploid.
How many chromosomes are there in each cell at the end of meiosis?
1N or half of the original 2N count of the organism in question.
What cell process is used to make gametes?
Gametes are Haploid (N) - From a Diploid (2N) cell, a cell must go through meiosis - From another Haploid cell, mitosis must occur to produce another cell.
