Abstract excerpt
A unique property of Drosophila melanogaster l(1)ts403 strain with the defect in heat shock protein system (HSP) is high frequency of losses and non-disjunction of sex chromosomes induced by heat shock (HS) (37 degrees C, 1 h). This effect was shown in only 6-14-th stages of oocytes. Anoxia was not effective in induction of these mutations. Successive action of anoxia and HS decreased loss frequency and...
