Frequency of Genetic Polymorphism: Implications for Mental Disease

  • Charles R. Shaw
Part of the Advances in Behavioral Biology book series (ABBI, volume 1)


The total number of genes occurring in the cells of higher animal organisms, such as man, is not accuratedly known. The figure most often quoted is 50,000, but this is no more than a slightly educated guess. The total amount of DNA contained in the nucleus would account for something like one hundred times that number of genes, but a large amount of the DNA, probably most of it, does not carry genetic information.
