Genetic characterization and bottleneck analysis of Korki Jonub Khorasan goats by microsatellite markers [Korki Jonub Horasan keçisinin mikrosatellit markörleriyle darboǧaz analizi ve genetik tani{dotless}mlanmasi{dotless}]

The present study was undertaken for population genetic analysis at molecular level to exploit the breed for planning sustainable improvement,conservation and utilization,which subsequently can improve the livelihood of its stake holders. iranian goat populations are recognized as an invaluable component of the world's goat genetic resources. the genetic characterization and bottleneck analysis in korki jonub khorasan (kjk) was analyzed using 13 microsatellite markers. the observed number of alleles ranged from 3 (oarae133) to 11 (tgla122) with a total of 98 alleles and mean of 7.54 alleles across loci. the overall heterozygosity,pic and shannon index values were 0.845,0.76 and 1.759 indicating high genetic diversity. only 4 out of 13 loci were in hardy-weinberg equilibrium. the mean fis was -0.059.only 3 loci had positive fis values and 10 loci had negative values. genetic bottleneck hypotheses were also explored. our data suggest that the kjk goats have not experienced a genetic bottleneck in the recent past.
