On May 30, 2003, Ewan Birney of the European Bioinformatics Institute, who had organized the pool, [2] announced the winner: Lee Rowen of the Institute for Systems Biology. [15] Rowen had guessed that the human genome would contain 25,947 genes, which was the closest to the estimated number of 24,847 given by the Ensembl genome database project.
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 ...
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 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.
The Selfish Gene is a 1976 book on evolution by ethologist Richard Dawkins that promotes the gene-centred view of evolution, as opposed to views focused on the organism and the group. The book builds upon the thesis of George C. Williams 's Adaptation and Natural Selection (1966); it also popularized ideas developed during the 1960s by W. D ...
