Abstract
The study investigates the intra-population and inter-population genetic
variations of the domestic goose populations of T?rkiye 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,
Aalm1b, 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.
