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.
1 For example, homozygous dominant (TT), heterozygous (Tt), homozygous recessive (tt). 2  Gene: a gene is a stretch of DNA that codes for a trait. 3  In molecular biology, the gene codes for a protein, which acts to bring about a trait.4  Locus: location (of a gene) on a chromosome. For example, height, color, whether the organism exhibits a trait. 2  Genotype: the genetic make up. 3  For example, homozygous dominant (TT), heterozygous (Tt), homozygous recessive (tt). 4  Gene: a gene is a stretch of DNA that codes for a trait.
