Combined Genetic Approaches to Elucidate Relations of Origin, Phenotype, Habitat and Climate Change

Abstract

Yasin M. Pala

Two main approaches, relying on only genetic drift and considering both genetic drift and mutations in equilibrium, are keys in revealing genetic distance and relevance among populations. Genetic relations and histories of communities can be unearthed by utilizing these methods accurately. For this reason, the equilibrium method should be definitely used to identify blood ties and migration waves. F_ST, therefore also phenotypes should be utilized in understanding habitats’ adaptational effects whereas F_ST and phenotypes are not sufficient to disclose blood ties. Thus bonds among migration, genotype, phenotype and origin will be resolved truly. Those are clear phenotypes extremely depend on habitats, especially climates as expected and genotypes hide collective origins over mutational roots. Then formation and evolution areas of populations can be detected via the equilibrium method and F_ST respectively. Even rates of genetic drifts can be calculated by measuring the alteration of phenotypes. Moreover some organisms’ genes could be regulated stably in the laboratory in part natural manner when habitats’ effects on genetic drifts were revealed.
