Detailed explanation-1: -2n represents the diploid chromosome number. In all sexually reproducing organisms, all body cells except the gametes contain diploid number of chromosomes (2n). The cells containing the diploid number of chromosomes are called diploid cells.

Detailed explanation-2: -"Normal” cells contain 2 full sets of chromosomes and are described as diploid or abbreviated as 2n. Most of your cells are diploid because they contain two sets of chromosomes. Each set of human chromosomes contains 23 chromosomes so most cells in your body have 46 chromosomes.

Detailed explanation-3: -The symbol 2n is used to represent the diploid number of an organism. For example, the cell below has a diploid number of 6. You would write this ….. The symbol n is used to represent the haploid number of an organism.

Detailed explanation-4: -Diploid (2n) chromosome numbers were determined from cells in late prophase and metaphase of mitosis.
