How many chromosomes do humans have?

Human have total 46 chromosomes i.e. 23 pairs. In males it is 22 pairs of autosomes +X and Y chromosomes and in females it is 22 pairs of autosomes + a pair of X chromosomes.

We have 46 chromosomes. They come as 23 pairs.

46. 

Note that the size of an organism hasnothing to do with its chromosome number.  (I find this interesting.)  A shrimp has 254 and a horse has 66.  Weird huh.....
