Polymorphism and Divergence of Multilocus DNA Markers in Sibling Species Chironomus riparius Meigen and Chironomus piger Strenzke (Diptera, Chironomidae)

Polymorphism and Divergence of Multilocus DNA Markers in Sibling Species Chironomus riparius... Intra- and interspecific variation and divergence of multilocus markers for genomic DNA of the sibling species from the thimmi group,Chironomus riparius and C. piger, were studied by PCR with arbitrary primers (RAPD). A high level of RAPD polymorphism was determined in both laboratory and natural populations of these species. The genetic distances were estimated between the C. riparius populations and between the sibling species C. riparius and C. piger. The genetic distance between C. riparius andC. piger was 4 to 5 times higher than that between the C. riparius populations. A comparison of the variation and divergence for the RAPD markers with those for other genomic markers—enzyme-coding genes and chromosomes (gene linkage groups)—showed that different components of the genome differed in their contribution to the genome divergence. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

Intra- and interspecific variation and divergence of multilocus markers for genomic DNA of the sibling species from the thimmi group,Chironomus riparius and C. piger, were studied by PCR with arbitrary primers (RAPD). A high level of RAPD polymorphism was determined in both laboratory and natural populations of these species. The genetic distances were estimated between the C. riparius populations and between the sibling species C. riparius and C. piger. The genetic distance between C. riparius andC. piger was 4 to 5 times higher than that between the C. riparius populations. A comparison of the variation and divergence for the RAPD markers with those for other genomic markers—enzyme-coding genes and chromosomes (gene linkage groups)—showed that different components of the genome differed in their contribution to the genome divergence.
