FITNESS OF MUTANTS CN AND VG IN LABORATORY POPULATIONS DROSOPHILA MELANOGASTER

Abstract

Изучали приспособленность мутантов cinnabar (сn) и. vestigial (vg) в линейных и гибридных лабораторных популяциях Drosophila melanogaster. Об относительной (дарвиновской) приспособленности судили по эффективности размножения мух в экспериментальных популяциях сn х vg. Для определения отдельных компонент приспособленности исследовали плодовитость и жизнеспособность (продолжительность жизни, устойчивость к голоданию) у линейных мутантов и их гибридов. Установили, что отбор действует против мутантов vg, которые уступают мутантам сn и гибридам по основным показателям приспособленности, кроме устойчивости к голоданию.

Mutants cinnabar (cn) and vestigial (vg) Drosophila melanogasterfitness has been studied. Relative (Darvin) fitness after efficiency of reproduction of flies has been investigated in experimental populations of cn x vg. Fecundity and viability (life-span, stability to starvation) at linear flies and their hybrids were studied in quality of separate component of fitness. It was proved that selection operates against the mutants of vg yielded to the mutants cn and the hybrids on the basic indexes of fitness, except the stability to starvation.

Досліджували пристосованість мутантів cinnabar (сn) і vestigial (vg) Drosophila melanogaster. Відносну (дарвінівську) пристосованість визначали за ефективністю розмноження мух у штучних популяціях сn х vg. У якості окремих компонент пристосованості вивчали плодючість та життєздатність лінійних мух і їх гібридів. Вста новлено, що добір діє проти мутантів vg, котрі поступаються мутантам сп і гібридам за основними показниками пристосованості, окрім стійкості до голодування.
