[Spatial organization of chromosomes in oocytes and spermatocytes in malaria mosquitos].

It is shown that prophase chromosomes of oocytes in Anopheles messeae ovaries do not form local chromocenters, unlike spermatocytes, in which chromosomes fuse in a joint centromeric assembly. This fact reflects the dynamic nature of the system of chromocenter formation in generative tissues. During analysis of interspecific hybrids F1 A. maculipennis x A. subalpinus, no conjugation of homeologous chromosomes was observed, and the latter remained separated from one another.
