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.
Genotype is what is there, though this would be in terms of genes not whole chromosomes. And phenotype is what is expressed. Also the eye color example is a good one though don't forget that this is determined by more than just two alleles of one gene, so it's a little simplistic but still a useful example. Genotype not being the same as Phenotype can get a little sticky once you get into codominance or genetic masking. More simply put, take the example of a heterozygote. The subject would have a dominant allele and a recessive one for a gene.
