Detailed explanation-1: -Chromosome: It is a thread-like structure composed of protein and a single molecule of DNA that transports genetic information from cell to cell. The term 2n: Denotes the diploid condition. It denotes that the cell has two sets of chromosomes. Human 46 chromosomes, for example, exhibit the 2n condition.

Detailed explanation-2: -The chromosomal diploid number in humans is 46 (i.e. 2n=46 chromosomes or 23 pairs of chromosomes). All the body cells like, blood cells, skin cells, muscle cells are diploid. Only sex cells or gametes are not diploid; sex cells are haploid.

Detailed explanation-3: -The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).

Detailed explanation-4: -Chromosomes in diploid cells are arranged in homologous pairs. The diploid chromosome number of a cell (2n) is the total number of chromosomes in a cell. In the case of humans, 2n = 46, meaning there are a total of 46 chromosomes in a diploid human cell.

Detailed explanation-5: -Diploid. A diploid cell has two complete sets of chromosomes. Most cells in humans are diploid, comprising 23 chromosome pairs, so 46 chromosomes in total. This is 22 pairs of autosomes and a pair of sex chromosomes.
