What happens to a 2n cell during meiosis?

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.
