[Comparative study of the somatic conjugation of chromosomes in the neural ganglia of male and female Drosophila melanogaster D-32].
The frequency of somatic conjugation of the 2nd and 3d chromosome pairs has been analysed in male and female neural ganglia from Drosophila melanogaster larvae D-32 line. The frequency of conjugation found for males was 1.5 times lower than for females. On this basis a supposition concerning less duration of homologous conjugation in males has been put forward. It is suggested that it is due to the differences in space arrangement of homologous chromosomes holding their conjugation.
