Sep 04, 2006 In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twentytwo of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.Human cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell. In addition to these, human cells have many hundreds of copies of the mitochondrial genome. Sequencing of the human genome has provided a great deal of a human body cell has 46 chromosomes

The human body cells each contain a total of 46 chromosomes, which are grouped into 23 pairs, one set from each parent. Each cell receives a chromosome carrying the same traits from both parents, which then forms a pair. There are 22 pairs of normal chromosomes, and 1 pair of sex chromosomes.

How can the answer be improved? Nov 11, 2008 Human cells have 46 chromosomes that are placed into 23 pairs, with one chromosome of each pair coming from the father and mother separately. Discover what an extra or missing chromosome causesa human body cell has 46 chromosomes Meiotic cells undergo a more complicated process to ensure the correct number of chromosomes. Here's what happens: At first the cells have the same number of chromosomes as mitosis.
