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 variability (vary + liable-to or capable of change) is the ability, i.e. capability of a biological system â individual and population â that is changing over time. The base of the genetic variability is genetic variation of different biological systems in space.Genetic variability is a measure of the tendency of individual genotypes in a population to vary from one another, also.Variability is different from genetic diversity, which is the amount of variation seen in a particular population.The variability of a trait describes how much that trait tends to vary in response to environmental and genetic influences. Homologous recombination is a significant source of variability. 2  During meiosis in sexual organisms, two homologous chromosomes from the male and female parents cross over one another and exchange genetic material.
