Gene flow is the source of genetic variation. Gene flow can be defined as the, introduction of new alleles to a population. Normally, this is because of simple migration. In this, new individuals of similar species enter into a population. Environmental conditions in their already existing home may have favored different forms of traits. Alleles belongs to these traits would be different from the alleles present in host population. When the new individuals interbreed with the host population, they produce new form of genes which is responsible for particular traits.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
