Here's a breakdown:
* Chromosomes: These are long strands of DNA that carry genetic information.
* Pairs: Humans are diploid organisms, meaning we have two copies of each chromosome. One copy comes from the mother, and the other from the father.
* 23 pairs: The 23 pairs of chromosomes include 22 pairs of autosomes (non-sex chromosomes) and one pair of sex chromosomes.
* Sex chromosomes: Females have two X chromosomes (XX).
It's important to note that this is only true for body cells (somatic cells). Gametes (sex cells like eggs) have only half the number of chromosomes (23).
