A large gene pool indicates extensive genetic diversity, which is associated with robust populations that can survive bouts of intense selection.Meanwhile, low genetic diversity (see inbreeding and population bottlenecks) can cause reduced biological fitness and an increased chance of extinction, although as explained by genetic drift new genetic variants, that may cause an increase in the ...
In population genetics, fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene in a given population to a situation where only one of the alleles remains. That is, the allele becomes fixed. [1]
The gene pool of a species or a population is the complete set of unique alleles that would be found by inspecting the genetic material of every living member of that species or population. A large gene pool indicates extensive genetic diversity, which is associated with robust populations that can survive bouts of intense selection.
Alternatively, if survivors of the bottleneck are the individuals with the greatest genetic fitness, the frequency of the fitter genes within the gene pool is increased, while the pool itself is reduced. The genetic drift caused by a population bottleneck can change the proportional random distribution of alleles and even lead to loss of alleles.
The project became more formalized with the creation of a website in 1993, followed by a series of books starting in 2000 by Wendy Northcutt. The criterion for the awards states: "In the spirit of Charles Darwin, the Darwin Awards commemorate individuals who protect our gene pool by making the ultimate sacrifice of their own lives. Darwin Award ...
Mating pool is a concept used in evolutionary algorithms and means a population of parents for the next population. [1] [2] The mating pool is formed by candidate solutions that the selection operators deem to have the highest fitness in the current population. Solutions that are included in the mating pool are referred to as parents.
Those in the dating pool who may consider themselves a potential victim of throning would be wise to address questions of wealth and status with their new suitors in the early going.
A mutation will increase genetic diversity in the short term, as a new gene is introduced to the gene pool. However, the persistence of this gene is dependent of drift and selection (see above). Most new mutations either have a neutral or negative effect on fitness, while some have a positive effect. [11]
