[Karyotypes and chromosome polymorphism of two phytophilous species of chironomids--Glyptotendipes mancunianus and G.imbecillis (Diptera, Chironomidae].
Detailed cytophotomaps of polytene chromosomes have been made for Glyptotendipes mancunianus (2n = 8) and G. imbecillis (2n = 8). In the karyotype of G. imbecillis a greater quantity of a near-centromere heterochromatin is noted. In the karyopool of G. mancunianus 10 sequences are revealed. Specimens with heterozygous inversions make 39%, the average number of heterozygous inversions per specimen is 0.34. In the karyopool of G. imbecillis 11 sequences have been met. Specimens with heterozygous inversions make 69%, the average number of heterozygous inversions per specimen is 1.68.
