SPATIAL ARRANGEMENT OF CHROMOSOMES IN OOC YTES AND SPERMATOCYTES MALARIA MOSQUITOS

It is shown that prophase chromosomes of oocytes in Anopheles messeae ovaries do not form local chromocenters, unlioke spermatocytes, in whi ch chromosomes fuse in a joint centromeric assembly, This fact reflect s the dynamic nature of the system of chromocenter formation in genera tive tissues. During analysis of interspecific hybrids F-1 A. maculpen nis x A. subalpinus, no conjugation of homeologous chromosomes was obs erved, and the latter remained separated from one another.
