The diploid number for humans is 46 chromosomes, which is written as 2n=462n=462n=46.

Quick Scoop

  • Diploid cells have two complete sets of chromosomes, one set from each parent.
  • In humans, those two sets make 23 pairs, for a total of 46 chromosomes in each typical body (somatic) cell.
  • Human haploid cells (egg and sperm) have just one set of chromosomes, so n=23n=23n=23.

In short: humans are 2n = 46, made of 23 matching chromosome pairs in most cells.
