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.
Scholarly peer review is the process of subjecting an author'sscholarlywork, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
