Humans typically have 23 pairs of chromosomes, for a total of 46 chromosomes in each body (somatic) cell.

Quick Scoop: Core Answer

  • Number of chromosome pairs in humans: 23.
  • Total number of chromosomes: 46 (because each pair has 2 chromosomes).
  • Of these, 22 pairs are autosomes and 1 pair is sex chromosomes (XX or XY).

Tiny Breakdown (So It Sticks)

  • You inherit 23 chromosomes from your mother and 23 from your father, which together form 23 matching pairs in your cells.
  • Pairs 1–22 are called autosomes; the 23rd pair determines biological sex (XX in most females, XY in most males).

Think of it like this: your genome is a “library” of 23 matched book pairs, one copy from each parent, making a shelf of 46 books total.

Little Extra: When The Number Changes

Most people have 23 pairs, but sometimes there can be an extra or missing chromosome.
For example, Down syndrome often involves an extra copy of chromosome 21 (three instead of a pair, called trisomy 21).

TL;DR: Humans have 23 pairs of chromosomes, which equals 46 chromosomes in total in a typical body cell.
