How many chromosomes do humans have? The typical number of chromosomes in a human cell is 46: 23 pairs, holding an estimated total of 20,000 to 25,000 genes. One set of 23 chromosomes is inherited from the biological mother (from the egg), and the other set is inherited from the biological father (from the sperm).
Exactly how many chromosomes we are talking about depends on the species. A mosquito has 6 chromosomes, a pea plant has 14, a sunflower 34, a human being 46, and a dog 78. Closely related species tend to have a similar number of chromosomes. For example, chimpanzees, our closest cousins, have 48 chromosomes in each of their cells. But aside from this general rule, there is very little rhyme or reason to how many chromosomes a species has.
