Genetically modified fish are used for scientific research, as pets, and as a food source. Aquaculture is a growing industry, currently providing over half of the consumed fish worldwide. [ 101 ] Through genetic engineering, it is possible to increase growth rates, reduce food intake, remove allergenic properties, increase cold tolerance, and ...
Mutation is a genetic operator used to maintain genetic diversity of the chromosomes of a population of an evolutionary algorithm (EA), including genetic algorithms in particular. It is analogous to biological mutation .

The human germline mutation rate is approximately 0.5×10 −9 per basepair per year. [1] In genetics, the mutation rate is the frequency of new mutations in a single gene, nucleotide sequence, or organism over time. [2] Mutation rates are not constant and are not limited to a single type of mutation; there are many different types of mutations.
A mutation in the protein coding region (red) can result in a change in the amino acid sequence. Mutations in other areas of the gene can have diverse effects. Changes within regulatory sequences (yellow and blue) can effect transcriptional and translational regulation of gene expression.
The man who authorities say tried to carry out a mass shooting in Yellowstone National Park last year spewed racist views months before his attempted attack, prosecutors said in court documents ...
