Definition: A diploid cell is a cell that contains two sets of chromosomes. One set of chromosomes is donated from each parent.
The diploid number of a cell is the number of chromosomes in the cell. This number is commonly abbreviated as 2n, where n stands for the number of chromosomes. For humans this equation would be 2n=46.

Humans have 2 sets of 23 chromosomes for a total of 46 chromosomes:
  • Autosomal chromosomes (non-sex chromosomes) - 22 sets of 2.
  • Sex chromosomes - 1 set of 2.
