Humans typically have 46 chromosomes in total, arranged in 23 pairs. These chromosomes are made up of long strands of DNA, which contain all the body's genes.
- Autosomes: 22 of these pairs, called autosomes, look the same in both males and females.
- Sex Chromosomes: The remaining pair, known as sex chromosomes, determines an individual's sex. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY).
