| chromosome numbers, sex determining systems, and patterns of the c-heterochromatin distribution in 13 species of lace bugs (heteroptera, tingidae). | the karyotypes, sex chromosome systems, and male meiotic patterns in 13 species belonging to 10 genera of the family tingidae were studied. data on eleven species, one subgenus, and 5 genera are presented for the first time, and the chromosome formula of acalypta parvula is revised. karyotypes of all species included six pairs of autosomes. most of the species displayed an xy sex chromosome system, in four species, belonging to genera of acalypta and kalama, the x0 system was found. male meiosis ... | 2001 | 11732164 |
