“…This interpretation was supported by additional analyses of allozymes coupled to morphometric analyses [19,20]. However, evidence for such an archipelago (as opposed to the Tanzanian case) of A. m. monticola type bees using allozymic [21,33], morphometric and mitochondrial DNA (mtDNA) [8,10,33,34] analyses of honeybees of other mountainous systems in Africa were equivocal in this regard.…”

“…The distribution of allele frequencies where the rare alleles are pooled is given in Figure 1. [21] and Anatolia ( [14]; and the present study), is common in A. m. ligustica [34] and A. m. carnica [35].

tivariate statistical analysis of morphometric data [30]. Honey bee races in this region include the subspecies Apis mellifera anatoliaca, A. m. caucasica, A. m. meda, and A. m. syriaca, which were considered by Ruttner [30] to form a basal branch (O) of the species. Another subspecies that is found in the European part of Turkey, i.e., Thrace, may be A. m. carnica, which belongs to the branch C of Ruttner's classification. INTRODUCTIONRuttner [30] claimed that southwest Asia is a zone of high morphological diversification and evolution for honeybees. Many clearly distinct races have evolved within this region, which includes a diversity of habitats. Asia Minor, including Anatolia, appears to be the genetic center for these honeybee subspecies according to the mul- Original articleGenetic and morphometric variation in honeybee (Apis mellifera L.) populations of Turkey Abstract -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 axis, and Anatolian honeybees were further separated along a second canonical axis. The observation of rare alleles in isoenzymes, detection of high genetic diversity and the presence of four known subspecies support the argument that Anatolia has been a genetic center for honeybee populations in the Near East.Apis mellifera anatoliaca / A. m. caucasica / A. m. meda / A. m. syriaca / population genetics / genetic variability / morphometry / electrophoresis / Turkey

“…The characters that contributed most to the discrimination were pilosity, body size and pigmentation, as known from honey bees in Tanzania (Meixner et al, 1989 Nunamaker and Wilson (1981 ) and Ndiritu et al (1986), the loci Est and HK were remarkably polymorphic. Polymorphism of HK in honey bees has been previously reported only from Africanized bees in South America (Del Lama et al, 1988, 1990 where several enzymes (ME, PGM) are fixed for one allele although they are reported to be polymorphic from Europe (Sheppard, 1988 (Meixner et al, 1989 (Ruttner, 1988) and thus less reliable in estimating relationships among taxonomic units, allozymes are estimated to be more neutral with respect to selection (Berlocher, 1984).…”

“…Although in the last decade allozyme analysis became a widely used instrument to study honey bee racial relationships (Badino et al, 1983(Badino et al, , 1984Cornuet, 1982; Sheppard and Berlocher, 1984and Berlocher, , 1985 Sheppard and McPheron, 1986), comparatively little experimental work has been done on allozymes of African honey bees (Ndiritu et al, 1986). Most of the knowledge accrued to date comes from studies on Africanized bees in South and Central America (Sylvester, 1982;Del Lama et al, 1988, 1990Sheppard et al, 1991) or comparisons of these bees with colonies obtained from South Africa (Nunamaker and Wilson, 1981), but no multi-locus study on a large collection of honey bees from Africa has been conducted.…”
