Subjects <strong>of</strong> Research:<br />

Meiotic division mechanism in Drosophila melanogaster.<br />

General Results 1993-1995:<br />

A common model <strong>of</strong> paring and crossing-over was suggested.<br />

Explanation <strong>of</strong> <strong>the</strong> mechanism <strong>of</strong> interchromosomal effect on<br />

crossing-over and <strong>the</strong> mechanism <strong>of</strong> suppressing crossing-over in<br />

chromosomal rearrangement was given. Some mutations<br />

transgressing <strong>the</strong> course <strong>of</strong> meiosis and mi<strong>to</strong>sis were obtained.<br />

Participation in State and International Programs:<br />

New Trends in Genetics<br />

Subjects <strong>of</strong> Scientific Collaboration:<br />

Genetical and cy<strong>to</strong>logical study <strong>of</strong> cell division mutants obtained in<br />

Drosophila melanogaster. The mutants obtained in <strong>the</strong> labora<strong>to</strong>ry can be<br />

provided for fur<strong>the</strong>r investigations.<br />

Cy<strong>to</strong>logical description <strong>of</strong> insertions <strong>of</strong> Y-material in<strong>to</strong> chromosome 2<br />

<strong>of</strong> Drosophila. The labora<strong>to</strong>ry can determine <strong>the</strong> character <strong>of</strong> <strong>the</strong><br />

inserted Y-material using differentiational staning techniques.<br />

Obtaining <strong>of</strong> abundant genetical data about recombination in Drosophila<br />

for determination <strong>of</strong> <strong>the</strong> interference in different regions.<br />

Subjects <strong>of</strong> Reseach:<br />

Functional organization <strong>of</strong> polytene chromosome:<br />

Molecular and cy<strong>to</strong>logical study <strong>of</strong> tissue - specific genes. Silk<br />

protein genes <strong>of</strong> special lobe <strong>of</strong> chironomid salivary gland as a model<br />

<strong>of</strong> study.<br />

Chromosomal evolution in chironomids: homologous rows <strong>of</strong> chromosomal<br />

variability. Effects <strong>of</strong> anthropogenic actions on chromosomal<br />

polymorphism in natural population.<br />

Mobile elements <strong>of</strong> chironomid: molecular structure, chromosomal<br />

localization and evolution.<br />
