title: [The dynamics of survival rate of experimental polulations of Drosophila melanogaster undergone to a chronic irradiation].
abstract: In genetically non-uniform populations Drosophila melanogaster in conditions of a chronic irradiation in a doze 10-11 sGy/generation dynamics parameters of populations was investigated. It is established, that number of individuals in irradiated populations is lower, than in control. It is revealed, that viability of populations undergone to a chronic irradiation depends on their genotype. The gradual increase in fruitfulness, viability of individuals and the decrease in a level of lethal mutations in a number of generations after an irradiation in small dozes is caused by adaptable opportunities of the populations.
