Karazin popup.description2 Objects under research; strains and hybrids of Drosophila melanogaster ,human cells. polytene chromosomes, seeds of wheat and sunflower. Aim of research;The aim of the work is further investigations of genetic,biological and cytological basis of quantity heterosis succession and non-specific firmless on model objects,cell and organism levels and also cytogenetic bases of plants ' radiation resistance.The ivestigation of droshophila. The influence of droshophila culture proof and the age of its parents on the expressiveness of eyeless (ey) and the decrease of polyteny level of giant chromosomes were investigated. The increase of ey expressiveness and decrease of the giant chromosome polyteny within the increase of culture proof were shown.Tough negative correlation between these indices is discovered. The life abilility of inbreds linease and droshophila hybrids and embrional elimination in laying of inbreds lineage in normal conditions and under He-Ne laser radiation were studied.The results obtained show that stimulation of breed-ability and life-ability in genetic variants,which are characterized in normal conditions by low level of indices under investigation ,allow to suggest that undesirable endogene particularities of an organism, caused by inbreds depression can be compensated with the help of laser irradiation.
