Human cells contain 23 pairs of chromosomes for a total of 46. There are 22 pairs of autosomes and one pair of sex chromosomes. The sex chromosomes are the X chromosome and the Y chromosome. If you are male you have the XY chromosome.. making you a male. If you are female you have the XX chromosome.. making you a female.
