Island's of the Bahamas. Abaco, to the east of Grand Bahama, also receives similar weather, though its easterly position means it has greater exposure to the north-easterly trade winds. While this tempers the extremes of temperature, it also means it is at greater risk of hurricanes.
Genetic pollution is the term of genetics in which the genetic information is transferred in to the organisms where it is not needed or where this information never existed before. This flow of genetic information is usually undesired and cannot be controlled.

These changes are due solely to chance factors. The smaller the population, the more susceptible it is to such random changes.n small, reproductively isolated populations, special circumstances exist that can produce rapid changes in gene frequencies totally independent of mutation and natural selection.
