Linkage disequlibrium in populations of Merodon avidus A. (Diptera, Syrphidae)

Milankov Vesna R., Ludoški Jasmina Lj, Vujić Ante A.

Analysis of the genetic structure in the populations of Merodon avidus A originated from the Dubašnica Mountain, Serbia (AADUB), Pindos Mountain Greece (AAPIN) and Morinj, Montenegro (AAMOR) was done. Based on the polyacrylamide gel electrophoresis out of 16 analyzed loci 10 izozymic loci were monomorphic: Aat, Fum, Hk-2, Hk-3, Idh-2, Mdh-1, Pgm, Sod-1, Sod-2 Sod-3. Nonrandom association between alleles of the Ao and Me in the AAMOR population has been registered. Significant association among alleles of the Ao and Mdh-2 loci in AADUB and Ao and Gpd-2 loci in AAPIN was found as well. Percent of the locus with observed significant gametic disequilibrium was from 16.7% in AAMOR to significant association of the only variable loci pair in AADUB and AAPIN.
