title: [Phototaxis and adaptation of the eyeless Drosophila melanogaster line].
abstract: An artificial selection on positive and negative phototaxis of eyeless (ey) Drosophila melanogaster line was carried out. Expression of the ey trait in imago was estimating during the selection. The fitness of the "+" and "-" selected lines was evaluated by such components as heat resistance, life span, fertility of flies. The genetic analysis of phototaxis inheritance was carried out. It was found that phototaxis selection results in changes of fertility whereas it doesn't affect other indices of fitness to environmental conditions as well as the ey expression. The main polygenic systems of phototaxis inheritance are located in chromosome 2 and chromosome 3.
