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. The impact
factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing
journals of similar kind. It reflects the average number of citations to recent
articles published in science and
social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the InstPharmacologyitute for Scientific Information. The impact
factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years. Citations are important for a journal to get impact factor. Impact
factor is a measure reflecting the average number of citations to recent
articles published in the journal. The impact of the journal is influenced by impact factor, the
journals with high impact
factor are considered more important than those with lower ones. To increase the visibility and ease of use of
open access scientific and scholarly
journals OMICS Group top online publishing
