Estimation of the genetic activity of heavy metal salts on changing of recombination parameters in drosophila

Abstract

The effect of various concentrations of heavy metals salts (lead and mercury nitrates) on recombination parameters in drosophila is studied. It was demonstrated that these compounds have genetic activity and increase the crossing-over frequency in zone y-v of chromosome 1 (X) of drosophila, reduce its variability, as well as induce a double crossing-over.
