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.
Peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and reduces the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by academic scholars and professionals.
