Humans have 22 pairs of homologous non-sex chromosomes (called autosomes), and one pair of sex chromosomes, making a total of 46 chromosomes in a genetically normal human.
Each member of a pair is inherited from one of the two parents. In addition to the 22 pairs of homologous autosomes, female humans have a homologous pair of sex chromosomes (two Xs), while males have an X and a Y chromosome.

∙ 12y agoChromosomes are composed of protein and DNA. The DNA controls the cell's functions and heredity. In human body (somatic) cells, there are two sets of 23 chromosomes, for a total of 46. Each set of 23 chromosomes contains 22 autosomes and 1 sex chromosome. One set of 23 chromosomes comes from the mother and one set comes from the father. Individuals with two X sex chromosomes are female, while individuals with one X and one Y sex chromosome are male.
