How Many Genes Does A Human Being Have?
The count of genes in a human being is between 20,000 to 25,000 genes. There are less then 3 billion base pairs. The total genes in an organism will be called genome. The density of genome is the number of genes per one million base pairs. So, the number of genes in a human genome is 20,000-25,000. The Human Genome project has had a great influence in determining the number of genes in a human body. This project was completed in 2005. The genome in every individual (human or not) is unique. Except identical twins who have similar or almost similar genomes, that makes them look alike. Human Genome project was undertaken by a privately owned company called Celera Genomics in 1998. Since, many other companies have shown interest in the development and research related to research in this area. Some of the other projects are International Hap Map Project, Personal Genome Project and Perlegen.
