Humans have 23 pairs of chromosomes, for a total of 46 chromosomes.
In fact, each species of plants and animals has a set number of chromosomes. A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39
Human somatic cells have 46 chromosomes(23 pair) but a gamete(germ cell) gets half the amount, i.e. 23 chromosomes, (one from each pair)
