Revision of the banding sequence pool and new data on chromosomal polymorphism in natural populations of Chironomus agilis Shobanov et Djomin, 1988 (Diptera, Chironomidae)

Abstract

Quantitative and qualitative analysis of chromosomal polymorphism in 19 natural populations of Ch. agilis had been performed. Most studied populations showed a medium level of chromosomal polymorphism: on average 45±3.0% of specimens are heterozygotes with 0.52±0.01 heterozygotic inversion per larvae. Besides inversions, B-chromosomes were found in two populations. The total number of banding sequences found in banding sequence pool of Ch. agilis is 16. Three banding sequences – p’agiB3, p’agiD3, p’agiF3 – are described for the first time.

“…2 ) Previously, p’ag2C1 was considered to be unique to the species, but recent data on chromosomal polymorphism of Ch. agilis ( Golygina and Ermolaeva 2021 ) have shown that a banding sequence identical to p’ag2C1 does exist in the banding sequence pool of Ch. agilis (p’agiC2), although up to now it has been found only once.…”
