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.
Genetic drift is a random process that can lead to large changes in populations over a short period of time. Random drift is caused by recurring small population sizes, severe reductions in population size called bottlenecks and founder events where a new population starts from a small number of individuals.enetic drift is a random process that can lead to large changes in populations over a short period of time.
