[Contibution of the X chromosme to the increased resistance of inbred Drosophila melanogaster hybrids to physical effects].
Effects of high sub-lethal temperature and UV-irradiation on surviving of inbred lines of Drosophila melanogaster and its F1 hybrids derived from reciprocal crosses between these lines are investigated. High resistance of F1 hybrids to these factors was observed as compared with that of parental inbred lines. D. melanogaster females in inbred lines and F1 hybrids were more resistant than males. Differences in the resistance between females and males were more pronounced in hybrids.
