One definition of a species is a group of natural populations whose individuals have the potential to interbreed and produce fertile offspring. Gene flow — also called migration — is any movement of individuals, and/or the genetic material they carry, from one population to another. Chromosomes have genes and within genes are allele's. 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. In nature, species could be considered as the biggest gene pool possible. A bottleneck effect is an ecological phenomenon in which the population of a species is drastically reduced to the point where the species is still able to carry on, but the genetic diversity of the species is severely limited. Definition of Gene pool. genetic variance: diversity of alleles and genotypes in a population.

GENE POOL (Biology) gene pool: the total pool of genes in a population Source: Jenkins, John B. Lecture Notes/Understandings. A large gene pool has extensive genetic diversity and is better able to withstand the challenges posed by environmental stresses. It is unlikely that a gene will be restored by chance mutation, and the only other way it can be restored is if an animal is introduced into the breeding population that carries that gene and who reproduces successfully. The gene pool of a biological species is the largest and most inclusive. ; allele frequency = the frequency of an allele, as a proportion of all the alleles of of a gene, in a population.. allele frequencies range from 0 to 1.0, or as a percentage One definition of a species is a group of natural populations whose individuals have the potential to interbreed and produce fertile offspring. The concept of gene pool was formulated by the Russian geneticist Alexander Sergeevich Serebrovsky, who coined the term genofond, the English translation of which is the “gene pool”. Moreover, they are competent to interbreed and produce fertile offspring in the process. Learner's definition of GENE POOL.
