... The genetic material is stored in the form of DNA in most organisms. In humans, the nucleus of each cell contains 3 × 109 base pairs of DNA distributed over 23 pairs of chromosomes, and each cell has two copies of the genetic material. This is known collectively as the human genome. The human genome ...

Genetic Algorithms
... Possible settings for a gene are called alleles, e.g. in the example above the alleles are 0s and 1s, and if a gene codes a trait then an allele is the trait instance. For binary chromosomes, the alleles “alphabet” consists of just two characters, 0 and 1; There might be bigger “alphabets” to repres ...

Meiosis and Mitosis

Meiosis is the process by which sex cells (gametes) are formed. A diploid progenitor cell generates fo ...

This idea is called the Hardy-Weinberg principle. The constant state of allele frequencies is called genetic equilibrium. This is a ...
