A Polecat-Ferret hybrid is a cross between a European polecat (''Mustela putorius'') and a ferret (''Mustela putorius furo''). Crossbreeds between the two animals typically have a distinct white throat patch, white feet and white hairs interspersed among the fur. It is currently impossible to distinguish pure polecats from hybrids through DNA analysis, as the two forms are too closely related and inter-mixed to be separated through modern genetic methods.〔(Polecat FAQs ) © The Vincent Wildlife Trust 2010〕 The advantages of polecat-ferret hybrids over pure ferrets include the hybrid's better eyesight, their greater physical capabilities and their more independent nature. The disadvantages are that hybrids are less willing to be handled, require rigorous enrichment routines in order to prevent boredom, refuse to enter unfamiliar holes and do not cope well with being caged.〔Schilling, Kim & Brown, Susan (2007) ''Ferrets for Dummies'', For Dummies, ISBN 0-470-13943-9〕 First-generation crossbreeds usually develop their wild parent's fear of humans if left with their mother during the critical socialisation period between 7½ and 8½ weeks of age.〔Poole TB (1972) ''Some behavioral differences between European polecat,'' Mustela putorius, ''ferret,'' M furo, ''and their hybrids''. J. Zool 166:25–35〕 In some parts of Britain, the escape of domestic ferrets has led to ferret-polecat crossbreeds living in the wild. Ferrets were likely first brought to Britain after the Norman conquest of England (in the 11th century) or as late as the 14th century.〔Davison, A., et al. (1999) ''(Hybridization and the phylogenetic relationship between polecats and domestic ferrets in Britain )'', Biological Conservation 87 :155–161〕 John George Wood wrote that polecat-ferrets were sometimes used by hunters alongside pure ferrets.〔Wood, Rev. J. G. (1870) ''Wood's Animal Kingdom''〕 In modern times, supposed ferret-polecat crossbreeds are occasionally advertised as superior to pure ferrets for the purposes of rabbiting, though actual crossbreeds are very likely to be less handleable, less willing to familiarise themselves with dogs, and are more likely to kill their quarry outright rather than simply flush it from its burrow.〔Plummer, David Brian (2001) ''In Pursuit of Coney'', Coch Y Bonddu Books, ISBN 0-9533648-8-7〕 ==See also== *Polecat-mink hybrid 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Polecat-ferret hybrid」の詳細全文を読む スポンサード リンク
