Each chromosome contains a section of your DNA. a human has 23 pairs of chromosomes, and each part contains instructions for different things. The 23rd chromosome is where the sex is decided in humans, as the pair is either XY for a male or XX for a female.

Different animals have different chromosome numbers, which is why they cannot breed with different species.
