Most people have 23 pairs of these. Women and men share 22. What are they?
Chromosome 22 Chromosome 22 Chromosome 22 is one of the 23 pairs of chromosomes in human cells. Humans normally have two copies of chromosome 22 in each cell. Chromosome 22 is the second smallest human chromosome (chromosome 21 being smaller), spanning about 49 million DNA base pairs and representing between 1.5 and 2% of the total DNA in cells. In 1999, researchers working on the Human Genome Project announced they had determined the sequence of base pairs that make up this chromosome. Chromosome 22 was the first human chromosome to be fully sequenced. Chromosome 22 was originally identified as the smallest chromosome.
Men Are from Mars, Women Are from Venus different, but are not "so" different that we cannot understand each other."
