The Turkish native sheep breeds, possibly being the neighbours of the earliest domesticated sheep populations, might be harbouring important genetic characteristics to be employed in the future for the improvement of sheep breeds. In order to design a conservation strategy, their genetic diversities must be determined. In the present study, based on three microsatellite loci, the genetic diversity of the Kivircik, Awassi, Akkaraman breeds (native) of Turkey as well as two of their crossbreeds Turkgeldi and Konya Merino were studied comparatively. It was observed that their heterozygoties are all high (0.6673-0.7822) compared to previously studied breeds, as expected for populations close to the center of domestication. Neighbour Joining (NJ) tree based on allele sharing distances indicated that the inertia of the breeds are not high. Yet, the genetic differentiations between the breeds based on pairwise F-ST (inbreeding coefficient) values are all significant. Furthermore, the three microsatellite loci could distinguish three groups of native breeds and their crossbreeds; 11) Awassi, 2) Kivircik-Turkgeldi and 3) Akkaraman-Konya Merino.


Genetic diversity of sheep breeds focusing on conservation research in turkey
Açan, Sinan Can; Togan, İnci Zehra; Öktem, Hüseyin Avni; Department of Biology (2012)
In the first part of the present study, samples of 13 native Turkish sheep breeds (n=628) were examined, individually and comparatively, with respect to their 19 microsatellite loci to characterize them by employing various statistical analyses. Low FST values, high mean number of alleles and allelic richness as well as results of Factorial Correspondence Analysis and Structure analyses showed the degree of admixture between native sheep breeds of Turkey, IVE and SAK were observed as the most distincts of t...
Genetic diversity of native and crossbreed sheep breeds in Anatolia
Koban, Evren; Togan, İnci Zehra; Department of Biology (2004)
In this study the genetic diversity in Turkish native sheep breeds was investigated based on microsatellite DNA loci. In total, 423 samples from 11 native and crossbreed Turkish sheep breeds (Akkaraman, Morkaraman, Kivircik, Ivesi, Dagliç, Karayaka, Hemsin, Norduz, Kangal, Konya Merinosu, Türkgeldi) and one Iraqi breed (Hamdani) were analyzed by sampling from breeding farms and local breeders. After excluding close relatives by Kinship analysis, the genetic variation within breeds was estimated as gene dive...
Genetic evidence for the distinctness of Kangal dogs
Altunok, V; Koban, E; Chikhi, L; Schaffer, A; Pedersen, NC; Nizamlioglu, M; Togan, İnci Zehra (2005-01-01)
The genetic diversity of Kangal dogs (n=23) was analysed using 100 canine microsatellites, and the results were compared to Central Anatolian feral dogs (n=51), Akbash dogs (n=6), and Turkish greyhounds (TG, n=3). The Kangal, Akbash, Turkish greyhound and feral dogs were found to be significantly different from each other by F-ST measure. Factorial Correspondence Analysis (FCA), which evaluated the span of genotypic variation between individual dogs, yielded 4 distinct groups of the animals. Group I was com...
Revealing the history of Anatolian sheep domestication by using retrovirus integrations
Ayanoğlu, İhsan Cihan; Togan, İnci Zehra; Department of Biology (2013)
In the present study, it was aimed to contribute to the understanding of evolutionary history of sheep by using endogenous Jaagsiekte sheep retrovirus (enJSRV) integrations in 220 samples from 11 Turkish sheep breeds (Karayaka, Dağlıç, Kıvırcık, Sakız, Akkaraman, İvesi, Norduz, Karagül, Hemşin, Gökçeada and Morkaraman) and also in 30 samples from Anatolian wild sheep (Ovis gmelinii anatolica). Retrotypes of individuals were determined based on enJSRV integrations. The genetic distances between breeds were c...
Genetic diversity pattern in Populus Nigra populations of two major river systems in Turkey
Çiftçi, Asiy; Kaya, Zeki; Department of Biology (2019)
European black poplar (Populus nigra L.) is an important tree species in terms of social, economic and ecological interest in Turkey. Although, poplar plantations in large areas meet the needs of the economy, the natural genetic resources of the species have been highly degraded due to anthropogenic effects and natural biological events. To assess genetic diversity structure of natural populations, 124 naturally distributed European black poplar trees from two major rivers (Kızılırmak and Göksu) in Turkey w...
