**Step-by-Step Text Solution:** 1. **Definition of Gene Migration:** Gene migration, also known as gene flow, refers to the movement of alleles (gene variants) from one population to another. This process can occur when individuals from one population migrate to another and breed with the local population. 2. **Mechanism of Gene Migration:** When a population of a species (let's say Species 1) migrates to a new location (e.g., an island), it can interact with the local population (e.g., Species 4). This interaction often involves hybridization, where the migrating individuals breed with members of the local population. ...

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
