Maziso ebhuruu aHusky anokwezva maziso. Mamwe marudzi mashoma embwa, akadai seAustralian Shepherd naCollie, anogonawo kuva nemaziso ebhuruu. Kana ari maSiberian Huskies, vatsvakurudzi vakasarudza zvino kuti mavara avo anowanzotungamirira kunei. Maererano neizvi, kune hukama hwepedyo nekudzokorora kweimwe nzvimbo pane chromosome 18. Genome yembwa inoparadzirwa pamusoro pehuwandu hwe78 chromosomes, 46 muvanhu uye 38 mumakati.
Mhando dzinoverengeka dzemajini, akadai seanonzi merle factor anokonzera maziso ebhuruu mune mamwe marudzi embwa, akange atozivikanwa, asi haaite basa muSiberian Huskies. Chikwata chinotungamirirwa naAdam Boyko naAaron Sams veEmbark Veterinary muBoston, Massachusetts, mutengesi wekuongorora imbwa DNA, ikozvino yakabatanidza imbwa dzinopfuura 6,000 dzine mavara akasiyana-siyana mukuongorora genome.
Nzvimbo yakapetwa kaviri yechromosome iri padyo neiyo ALX4 gene, iyo inoita basa rakakosha mukukura kwemaziso mumhuka dzinoyamwisa, vanoongorora vanoshuma mujenari PLOS Genetics. Nekudaro, havasi vese maHuskies vane genetic variant vane maziso ebhuruu, saka mamwe aimbozivikanwa genetic kana zvakatipoteredza zvinhu zvinofanirwa kuitawo basa. Kazhinji mhuka ine ziso rimwe rebrown uye rimwe rebhuruu.
