Nikeza uhlu oluhlukaniswe ngama-comma lwezakhi zofuzo ezihlukene ezithonya imibala yejazi lehhashi ngokombhalo
Context:Amahhashi anezinhlobonhlobo zemibala yoboya nezimpawu ezihlukile, ezichazwe ngamagama akhethekile. Ngokuvamile, ihhashi lihlukaniswa kuqala ngombala wengubo yalo, ngaphambi kohlobo noma ubulili balo. Amahhashi anombala ofanayo angahlukaniswa ngemibala emhlophe, yona kanye nemidwebo ehlukahlukene yamabala, efakwa njengefa ngokwahlukana nombala wengubo. Kuye kwatholakala izakhi zofuzo eziningi ezibangela imibala nemiklamo yezingubo zamahhashi. Ukuhlolwa kwezakhi zofuzo kwamanje kungaveza okungenani ama - allele angu - 13 ahlukahlukene athonya umbala wengubo, futhi ucwaningo luyaqhubeka luthola izakhi zofuzo ezintsha ezihlobene nezimfanelo ezithile. Imibala eyisisekelo yoboya obumnyama nobumnyama inqunywa yi-gene elawulwa yi-Melanocortin 1 receptor, eyaziwa nangokuthi "i-extension gene" noma "red factor", njengoba ifomu layo lokuhlehla "libomvu" (i-chestnut) futhi ifomu layo eliyinhloko limnyama. Amanye ama-gene alawula ukucindezelwa kombala omnyama kuya kumbala ophawulekayo okuholela ekutholeni i-bay, amaphethini wokubona njenge-pinto noma i-leopard, ama-gene okuhlanjululwa njenge-palomino noma i-dune, kanye nokwenza mpunga, nazo zonke ezinye izici ezakha imibala eminingi yezinwele ezitholakala emahhashini.
