ANALYSIS OF GENETIC VARIATIONS IN TURKISH DOMESTIC GOOSE POPULATIONS AND CHINESE × EMBDEN CROSSES USING MICROSATELLITE MARKERS.

The study investigates the intra-population and inter-population genetic variations of the domestic goose populations of Türkiye and the commercial Chinese - Embden cross genotypes using microsatellite markers. DNA samples were collected from 110 geese of four different populations. The populations' genetic diversity is assessed using the Ans02, Ans17, Ans25, Aalκ1b, Aph19b, and TTUCG5 microsatellite loci. The highest number of alleles were detected at the Ans25 (28) locus, while the Aph19b (14) locus had the lowest. Wright's F-statistics are calculated separately for each locus without discriminating against the populations. The FST value varied between 0.038 and 0.105 and had positive values in all loci. The number of migrants (Nm) ranged from 2.12 to 6.34. Structure and principal coordinates analysis indicated that the Native population had distinct characteristics from the other populations. The number of shared alleles among populations is accepted as an indicator of genetic erosion in native goose populations. This study is one of the first reports that exotic breeds genetically polluted Turkish native populations. [ABSTRACT FROM AUTHOR]
