Abstract: In the present study, genetic diversity and population structure of Holstein Friesian and three native cattle breeds of Turkey including Turkish Grey Steppe, Eastern Anatolian Red and Anatolian Black were assessed. Totally 120 individuals of 4 breeds were genotyped using 20 microsatellite markers and 204 different alleles, of which 31 were private alleles, were detected. The average observed and expected heterozygosity values were 0.63 and 0.74, respectively. Observed heterozygosity at the marker level ranged from 0.30 (DRBP1) to 0.88 (ILSTS011), while expected heterozygosity ranged from 0.51 (INRABERN172) to 0.88 (SPS113). Inbreeding coefficient values for Turkish Grey Steppe, Eastern Anatolian Red, Anatolian Black and Holstein Friesian were 0.216, 0.202, 0.128 and 0.069, respectively. The lowest pairwise FST value (0.030) was detected between Turkish Grey Steppe and Anatolian Black breeds, while the highest value (0.070) was detected between Turkish Grey Steppe and Holstein Friesian. Results of structure and factorial correspondence analysis revealed that Turkish native cattle breeds and Holstein Friesian were genetically different enough to separate the two breeds. Results of bottleneck analysis indicated heterozygosity deficiency in Turkish Grey Steppe (P < 0.05).
