(2) Subject of Research:

Meiotic division mechanism in Drosophila melanogaster.

(3) General Results 1993-1995:

A common model of paring and crossing-over was suggested. Explanation of the mechanism of interchromosomal effect on crossing-over and the mechanism of suppressing crossing-over in chromosomal rearrangement was given. Some mutations transgressing the course of meiosis and mitosis were obtained.

(5) Participation in State and International Programs:

New Trends in Genetics

(6) Subjects of Scientific Collaboration:

Genetical and cytological study of cell division mutants obtained in Drosophila melanogaster. The mutants obtained in the laboratory can be provided for further investigations.
Cytological description of insertions of Y-material into chromosome 2 of Drosophila. The laboratory can determine the character of the inserted Y-material using differentiational staning techniques.
Obtaining of abundant genetical data about recombination in Drosophila for determination of the interference in different regions.
