We have 23 pairs of chromosomes per cell, and there are great costs to exceeding this ideal number. Having odd numbers of certain chromosomes leads to genetic disorders like Down syndrome, while babies with three of every chromosome – triploids – tend to be lost to miscarriage or die within months.

Chromosomes also contain chemical substances that govern the function of genes. The human body consists of millions of cells; each cell (liver, intestinal etc) contains 23 pairs of chromosomes except for germ cells (egg and sperm) and red blood cells. Thus a total of 46 chromosomes are present in human cells.

Humans usually have 22 pairs of homolog chromosomes (autosomes) and as sex chromosomes 2 x chromosomes (in female), or 1 x and 1 y chromosome (in males), thus in total 46 chromosomes per body cell (see human karyogram; 2n = 46) and 92 chromatids per cell after replication.

The DNA sequences of homologous chromosomes are usually not exactly identical. The nuclei of most human cells contain 46 chromosomes. These 46 chromosomes consist of 23 pairs of homologous chromosomes, or homologs, meaning each of these pairs are alike, but not necessarily identical.

Human somatic cells have 46 chromosomes, including 22 homologous pairs and one pair of nonhomologous sex chromosomes. This is the 2n, or diploid, condition. Human gametes have 23 chromosomes, one each of 23 unique chromosomes. This is the n, or haploid, condition.
