We analyzed the genetic structures of 11 honeybee (Apis mellifera) populations from Türkiye and one population from Cyprus using 9 microsatellite loci. Average gene diversity levels were found to change between 0,542 and 0,681. Heterozygosity levels, mean number of alleles per population, presence of diagnostic alleles and pairwise FST values confirmed the mitochondrial DNA finding that Anatolian honeybees belong to north Mediterranean (C) lineage. We detected a very high level of genetic divergence among populations of Türkiye and Cyprus based on pairwise FST levels (between 0,0 and 0,2). Out of 66 population pairs 52 were found to be genetically different significantly. This level of significant differentiation has not been reported yet in any other study conducted on European and African honeybee populations. High allelic ranges, and high divergence indicate that Anatolia is a genetic centre for C lineage honeybees. We suggest that certain precautions should be taken to limit or forbid introduction and trade of Italian and Carniolan honeybees to Türkiye and Cyprus in order to preserve genetic resources formed in these territories in thousands of years. Effectivity at previously isolated regions in Artvin, Ardahan and Kırklareli was confirmed by the high genetic differentiation in honeybees of these regions. Genetically differentiated Karaburun and Cyprus honeybees v and geographical positions of the regions make these zones first candidates as new isolation areas.

Genetic structure of honeybee, Apis mellifera L. (Hymenoptera : Apidae) populations of Turkey inferred from microsatellite analysis Bodur, Cagri; Kence, Meral; Kence, Aykut (2007-01-01) We analyzed the genetic structure of 11 honeybee (Apis mellifera L) populations from Turkey and one from Cyprus using 9 microsatellite marker loci. Heterozygosity levels, mean number of alleles per population, number of diagnostic alleles, and pairwise F-ST values were computed for the populations studied. Heterozygosity levels were found to range between 0.54 and 0.68. We detected high levels of genetic divergence among the populations based on pairwise F-ST values; 50 of 66 pairwise F-ST values were signi...
Mitochondrial dna (mtdna) haplogroup composition in Turkish sheep breeds Yüncü, Eren; Togan, İnci Zehra; Department of Biology (2009) In the present study, haplogroup composition of five native Turkish sheep breeds, (Karayaka, Akkaraman, Gökçeada, Dağlıç, Morkaraman) and two sheep breeds from neighboring countries (Herik from Iran, samples from Azerbaijan) were determined by single strand length polymorphism (SSCP) analysis of mitochondrial DNA (mtDNA) NADH dehydrogenase subunit 4 (ND4) region and restriction fragment length polymorphism (RFLP) analysis of mtDNA control (CR) region. Results of the SSCP and RFLP approaches were found to be...
Genetic relationships among perennial and annual Cicer species growing in Turkey as revealed by allozymes Sudupak, MA; Kence, Aykut (Springer Science and Business Media LLC, 2004-05-01) Allozyme polymorphisms were used to assess genetic variation and relationships among ten Cicer species ( annuals and perennials) growing in Turkey. Using seven enzyme systems, 12 putative scorable loci were detected and surveyed for polymorphism in an accession collection including wild and cultivated forms. Variation was generally low within accessions and species, but common between species. Cluster analysis based on the pairwise genetic distance coefficients (Nei 1978) among accessions and species using ...
Comparative analyses for the Central Asian contribution to Anatolian gene pool with reference to Balkans Berkman, Ceren Caner; Togan, İnci Zehra; Department of Biology (2006) Around 1000 ya, Turkic language started to be introduced to Turkey and Azerbaijan (Region of language replacement, RLR) in parallel with the migrations of Turkic speaking nomadic groups from Central Asia. The Central Asian contribution to the RLR was analyzed with four admixture methods considering different evolutionary forces. Furthermore, the association between the Central Asian contribution and the language replacement episode was estimated by comparatively analyzing the Central Asian contribution to R...
Genetic and morphometric variation in honeybee (Apis mellifera L.) populations of Turkey Kandemir, I; Kence, M; Kence, Aykut (Springer Science and Business Media LLC, 2000-05-01) Six enzyme systems were studied to determine the genetic variability in honeybee populations in Turkey. Ten morphometric characters were also measured to determine the extent of morphometric variation. Out of six enzyme systems, four were found to be polymorphic with 16 allozymes. The average heterozygosity was calculated as 0.072 +/- 0.007. Morphometric and electrophoretic variables were equally effective in discriminating honeybee populations. European and Anatolian honeybees were separated on the first a...
