Question

Difference between n, 2n and n+n conditions.

Answer 1

1.The n represents the haploid condition. In this condition, the cell possesses half number of chromosomes. For example, 23 chromosomes represent haploid (n) condition in humans. 2.The 2n represents the diploid condition. In this condition, the cell possesses two sets of chromosomes. ​For example, 46 chromosomes represent diploid (2n) condition in humans. 3.The n+n represents dikaryotic condition. In this condition, an intervening stages occurs where cell possesses two nuclei per cell and is called dikaryon. Later the two nuclei fuse and the cell becomes diploid. It occurs mainly in classes and Basidiomycetes of fungi. Hope this information will clear your doubts about the difference between n, 2n and n+n conditions.
