Amehlo kaHusky aluhlaza okwesibhakabhaka adonsa amehlo. Kuphela ezinye izinhlobo zezinja ezimbalwa, njenge-Australian Shepherd kanye ne-Collie, ezingaba namehlo aluhlaza. Ngokuqondene namaHuskies aseSiberia, abacwaningi manje sebenqume ukuthi umbala wabo uvame ukuholela kuphi. Ngokwalokhu, kunobudlelwane obuseduze nokuphindwaphindwa kwesifunda esithile ku-chromosome 18. I-genome yezinja isatshalaliswa phezu kwengqikithi yama-chromosome angu-78, angu-46 kubantu kanye nama-38 emakati.
Izinhlobo eziningana zofuzo, ezifana nalokho okubizwa ngokuthi i-merle factor ebangela amehlo aluhlaza ezinhlotsheni ezithile zezinja, zase zaziwa kakade, kodwa azidlali indima kumaHuskies aseSiberia. Ithimba eliholwa u-Adam Boyko no-Aaron Sams be-Embark Veterinary e-Boston, Massachusetts, umphakeli wokuhlolwa kwe-DNA yezinja, manje selihlanganise izinja ezingaphezu kuka-6,000 ezinemibala yamehlo ehlukene ekuhlaziyeni kofuzo.
Isifunda esiphindwe kabili se-chromosome siseduze nesakhi sofuzo se-ALX4, esidlala indima ebalulekile ekuthuthukisweni kwamehlo ezilwaneni ezincelisayo, kubika abacwaningi ephephabhukwini i-PLOS Genetics. Nokho, akuwona wonke ama-Huskies anofuzo oluhlukile anamehlo aluhlaza, ngakho-ke ezinye izici zofuzo ezazingaziwa ngaphambili noma zemvelo nazo kufanele zidlale indima. Ngokuvamile isilwane sineso elilodwa elinsundu kanye nelinye eliluhlaza okwesibhakabhaka.
