title: [Genetics of the cell cycle: adaptive modification of the cycB2g mutation expression in dividing cells of Drosophila melanogaster].
abstract: The effect of mutation CycB2g on mitosis in neural ganglia and imaginal disks was studied in third-instar larvae of Drosophila melanogaster. Chromosome condensation and segregation were shown to be impaired in dividing cells of mutant larvae. During the three-year period of maintenance of the mutation in heterozygote, frequencies of some defects decreased via cellular adaptive modification.
