The following requirements apply to all mutation operators used in an EA: [2] [3] every point in the search space must be reachable by one or more mutations. there must be no preference for parts or directions in the search space (no drift). small mutations should be more probable than large ones.
This indirect encoding is believed to make the genetic search more robust (i.e. reduce the probability of fatal mutations), and also may improve the evolvability of the organism. [ 26 ] [ 27 ] Such indirect (also known as generative or developmental) encodings also enable evolution to exploit the regularity in the environment. [ 28 ]
Furthermore, the application of DNA shuffling by molecular breeding on multiple parent adeno-associated virus (AAV) vectors was employed to generate a library of ten million chimeras. [29] The advantageous attributes obtained include increased resistance to human intravenous immunoglobulin (IVIG) and the production of cell tropism in the novel ...
A germline mutation in the reproductive cells of an individual gives rise to a constitutional mutation in the offspring, that is, a mutation that is present in every cell. A constitutional mutation can also occur very soon after fertilization , or continue from a previous constitutional mutation in a parent. [ 90 ]
Types of mutations that can be introduced by random, site-directed, combinatorial, or insertional mutagenesis. In molecular biology, mutagenesis is an important laboratory technique whereby DNA mutations are deliberately engineered to produce libraries of mutant genes, proteins, strains of bacteria, or other genetically modified organisms. The ...
There are several methods, or forms, of mutation that exist including spontaneous mutation, errors during replication and repair, as well as mutation due to environmental effects. [8] These origins of mutations can cause many different types of mutations which influence gene expression on both large and small scales.

Genetic programming (GP) is an evolutionary algorithm, an artificial intelligence technique mimicking natural evolution, which operates on a population of programs.It applies the genetic operators selection according to a predefined fitness measure, mutation and crossover.
