Amehlo aluhlaza kaHusky atsala amehlo. Zimbalwa ezinye iindidi zeenja, ezifana neAustralian Shepherd kunye neCollie, ezinokuba namehlo aluhlaza. Ngokuphathelele i-Siberian Huskies, abaphandi ngoku baye bafumanisa ukuba umbala wabo uhlala ukhokelela phi. Ngokwale nto, kukho ubudlelwane obusondeleyo kunye nokuphindaphinda ummandla othile kwi-chromosome 18. I-genome yezinja isasazwa kwi-chromosomes ye-78, i-46 kubantu kunye ne-38 kwiikati.
Iintlobo ezininzi zofuzo, ezifana nento ebizwa ngokuba yi-merle factor ebangela amehlo aluhlaza kwiintlobo ezithile zezinja, zazisele zisaziwa, kodwa azidlali indima kwi-Huskies yaseSiberia. Iqela elikhokelwa ngu-Adam Boyko kunye no-Aaron Sams we-Embark Veterinary eBoston, eMassachusetts, umthengisi we-dog DNA tests, ngoku iquka izinja ezingaphezu kwe-6,000 ezinemibala eyahlukeneyo yamehlo kuhlalutyo lwe-genome.
Ummandla ophindwe kabini we-chromosome usondele kwi-ALX4 gene, edlala indima ebalulekileyo ekuphuhliseni amehlo kwizilwanyana ezincelisayo, abaphandi babika kwiphephancwadi i-PLOS Genetics. Nangona kunjalo, ayizizo zonke ii-Huskies ezinokwahluka kofuzo zinamehlo aluhlaza, ngoko ke ezinye izinto ezazingaziwa ngaphambili zofuzo okanye zokusingqongileyo kufuneka zidlale indima. Amaxesha amaninzi isilwanyana siba neliso elimdaka ngebala elinye libe luhlaza okwesibhakabhaka.
