Bahamas Local, however, reports that a hurricane occurs about every three years with a major tropical storm every 12 years. Andros, Abaco and Grand Bahama are ranked in the top 10 places hit by tropical systems in the North Atlantic.
An example of a botanical genetic polymorphism is heterostyly, in which flowers occur in different forms with different arrangements of the pistils and the stamens. The system is called heteromorphic self-incompatibility, and the general 'strategy' of stamens separated from pistils is known as herkogamy.enetic polymorphism is actively and steadily maintained in populations by natural selection, in contrast to transient polymorphisms where a form is progressively replaced by another. By definition, genetic polymorphism relates to a balance or equilibrium between morphs.
Single nucleotide polymorphisms, frequently called SNPs (pronounced âsnipsâ), are the most common type of genetic variation among people. Each SNP represents a difference in a single DNA building block, called a nucleotide.
