Abstract

Sa pojačanim onečišćenjem okoliša koji uzrokuje čovjek, razni organizmi se moraju nositi na razne načine. Samo onečišćenje može imati direktan ili indirektan utjecaj. Kao direktan utjecaj navode se razne mutacije i oštećenja DNA molekule i kromosoma, a kao indirektan utjecaj genetski drift i genetska adaptacija. Genetska adaptacija obuhvaća brze genetske promjene koje odgovaraju na prirodne promjene i koje će omogućiti bolju vijabilnost nekog organizma, odnosno populacije. Međutim genetske adaptacije se ne mogu stalno odvijati, jer postoji spora selekcija koji eliminira jedinke podložne mutacijama. Komparativne analize nam omogućuju da se rezultati dobiveni na jednim genima kandidatima primjene i na druge organizme uključujući i vrste koje nisu modelni organizmi.

Abstract (english)

With substantial and increasing enviromental pollution which is caused by man, different organisms have to cope with it in various ways. Contamination itself may have direct or indirect influence. Direct effects are set of various mutations and lesions which implicate DNA molecules and chromosomes, and indirect effects are genetic drift and genetic adaptation. Genetic adaptation includes rapid genetic changes that are response to environmental changes, and that will provide better viability for some organism or population. However, genetic adaptation can not be conducted to infinity because there is a slow selection, that eliminates the individuals subjected to mutations. Comparative analysis make it possible to apply results, which are obtained in a single application of candidate loci, on other organisms, including species that are not model organisms.
