Genetic polymorphism definition biology
WebDefinition [ edit] A polyphenism is the occurrence of several phenotypes in a population, the differences between which are not the result of genetic differences. [2] For example, crocodiles possess a temperature-dependent sex determining polyphenism, where sex is the trait influenced by variations in nest temperature. WebWhether a cSNP affects a phenotype, depends on the amino acid that is changed by the polymorphism. About one-half of missense mutations that are SNPs are estimated to cause genetic disease in humans. A non-coding SNP can also affect gene function if it is located in the promoter region or in the gene regulatory region.
