What happens to a 2n cell during meiosis?

Answer 1

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.

Answer 2

Generally, 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.

Answer 3

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.

Answer 4

During meiosis, a 2n cell undergoes two rounds of cell division to produce four haploid (n) daughter cells. This process results in genetic variation due to crossing over and independent assortment of chromosomes.

Answer 5

A cell with 2n chromosomes is called a diploid.

(in humans it means they have 46 chromosomes)

Answer 6

2n stands for dipoid and n stands for haploid.

Answer 7

A 2n cell divides into four nonidentical 1n cells during meiosis.

Answer 8

in meiosis, however, you start with a diploid cell that divides twice to produce two haploid cells.

Answer 9

Simple mitosis.
