The spread of genes from one breeding populatoni to another by migration which may result in change in gene frequency is :

Fill up the balnks in the following paragraph by selecting the correct option. When migration of a section of population to another place and population occurs, I change in the original as well as in the new population new genes/ alleles are added to the ii, population and these are lost from the population. These would be a iv if this gene migration, happens multiple times. if the same change occurs by chance, it is called v. sometimes the change in allele frequency is so different in the new sample of population that they become a diffrent species. The original drifted population becomes founders and the effect is called vi
