उत्तर
The diploid (2n) number of chromosomes for humans is 46.
Explanation:
The diploid (2n) number refers to the total number of chromosomes found in a typical human body cell, which consists of two complete sets, one inherited from each parent. In humans, this total is 46 chromosomes, organised into 23 pairs. Of these, 22 pairs are autosomes (non-sex chromosomes), and one pair consists of sex chromosomes (XX or XY). In contrast, human gametes (sperm and egg cells) are haploid (n) and contain only 23 chromosomes.
