Явище «мутаційного спалаху» у природних популяціях Drosophila melanogaster України
Aims. Our goal was to investigate the rate of mutational variation in the wild populations of Drosophila melanogaster in Ukraine. Methods. We studied representatives from the wild populations across different regions of Ukraine and Switzerland in August-September of the years 2011 and 2012. All flies were analyzed using the binocular microscope for the appearance of visible phenotypic alteration. If found, the fly was isolated and breeded for diagnosing if the particular trait was able to be inherited to descendants.
Results. The infraction of 2nd longitudinal vein was found at 0,1-2,3% frequency among analyzed imagoes, that suggests an interpretation of this event as the "mutational burst" that might have global pattern.
