THE INFLUENCE OF THE MUTATIONS AND HETEROZYGOSIS ON THE SOME CHARACTERISTIC OF BEHAVIOR IN DROSOPHILA MELANOGASTER

Abstract

The aim of this work is to study the influence of the mutation and the heterozygosis on the sexual and locomotive activity Drosophila melanogaster. It’s been determined that the given mutations bring negative influence to the male sexual activity; however no influence had been noticed as on the sexual receptivity of the female except in the case of females of lines ebony and black. An increase in the level of heterozygosis as a rule leads to an increase in the female receptivity as compare to both the two parents′ forms and also leads to an increase in male sexual activity; for the hybrids the meaning of “sexual activity” is closer to the meaning of lines Canton-S. It’s been determined that for all mutant lines locomotive activity exceeds females locomotive activity lines Canton-S except those of lines ebony. For males, locomotive activity of mutant line exceeds the activity of the wild type only on lines brown and black. In the research, no authentic maternal or paternal effect for the study of the symptom has been declared.
