Y-chromosome microsatellite variation in Italian wolves: A contribution to the study of wolf-dog hybridization patterns

摘要: One major concern in wolf (Canis lupus) conservation is the risk of genetic contamination due to crossbreeding with domestic dogs. Although monitoring populations has become widely used, behavioural mechanisms involved wolf-dog hybridization and detrimental effects introgression are poorly known. In this study we analysed Y-chromosome microsatellite variation recovering Italian population detected strikingly different allele frequencies between wolves Four Y haplotypes were found 74 male wolves, all them present a focus Apennines. On other hand, only 1 haplotype was recolonizing from Western Alps. The most common sample dogs, also 5 2 which revealing signature recent hybridization. Moreover, another suspect hybrid carried private possible canine origin. These results give support idea that female can breed stray dogs wild. contrasts previously observed lack mitochondrial variation. Further investigations needed clarify at what extent historical or events may have contributed diversity. conclusion, two molecular markers employed represent effective means trace directional into lineage noteworthy advantage being suitable for analyses on low-quality DNA samples.
