Intshayelelo: Imfihlelo yezinja ezinamehlo aluhlaza
Amehlo aluhlaza ezinjeni yinto enomdla eye yadida abafuyi, abaphandi kunye nabathandi bezinja ngokufanayo. Ngelixa ezinye iintlobo zeenja ziyaziwa ngamehlo azo aluhlaza, ezinye zinokuba nombala wamehlo okhethekileyo ngenxa yokuguqulwa kofuzo. Nangona ubuhle bamehlo aluhlaza, kukho iinkxalabo zempilo ezinxulumene nale mpawu kwizinja. Kweli nqaku, siza kuphonononga imfuzo, iimpembelelo zempilo, kunye nokubaluleka kwamehlo aluhlaza ezinjeni.
I-Genetics yoMbala wamehlo kwizinja
Umbala wamehlo enja unqunywe ngumlinganiselo kunye nokusabalalisa i-pigments kwi-iris. Ezona ntlobo ziphambili zemibala yebala yi-eumelanin, evelisa imibala emdaka okanye emnyama, kunye nepheomelanin, evelisa imibala emthubi, ebomvu okanye e-orenji. Isixa sezi pigments silawulwa yimfuza emininzi, kuquka i-OCA2 gene, ejongene nokudala nokusabalalisa i-melanin. Ezinjeni, kukho iiallele ezimbini zejini ye-OCA2: enye evelisa i-melanin kunye nenye engayiveziyo. Ubukho okanye ukungabikho kwezi alleles kuqinisekisa ukuba amehlo enja aya kuba blue, brown, okanye omnye umbala.

Kwizinja, amehlo aluhlaza abangelwa ukungabikho kwe-melanin kwi-iris. Oku kuthetha ukuba ukukhanya okungena esweni kuthe saa endaweni yokufunxa, ukunika amehlo umbala oluhlaza okanye ongwevu. Amehlo aluhlaza axhaphake kakhulu kwezinye iindidi kunezinye, kwaye angenzeka ngenxa yotshintsho lwemfuza. Ngokomzekelo, i-merle gene, eyenza ipateni yengubo yebhatyi, inokuchaphazela amehlo, ibangele ukuba ibe luhlaza okwesibhakabhaka okanye inxalenye eluhlaza okwesibhakabhaka.
Inzala yeNja eneBlue-Eyed
Iintlobo ezininzi zeenja ziyaziwa ngamehlo azo aluhlaza, kuquka i-Siberian Husky, i-Alaskan Malamute, kunye ne-Australian Shepherd.

Nangona kunjalo, ayizizo zonke izinja ezinamehlo aluhlaza, kwaye ezinye iintlobo ezixubileyo zinokuba nalo mbala wamehlo ukhethekileyo.
Iinkxalabo ngeMpilo enamehlo aBlue kwizinja
Nangona amehlo aluhlaza mahle, anokuba luphawu lweengxaki zempilo ezinjeni. Izinja ezinamehlo aluhlaza zityekele ngakumbi kwiimeko ezithile zamehlo, njenge-cataract, iglaucoma, kunye ne-iris coloboma. Ezi meko zinokubangela ukulahleka kombono okanye ukungaboni, ngoko kubalulekile ukubeka iliso kwinja yakho enamehlo aluhlaza malunga naziphi na iimpawu zenkathazo.
Ukubaluleka kwamehlo aBlue kwiintlobo ezahlukeneyo
Amehlo aluhlaza anokuba neentsingiselo ezahlukeneyo kwiintlobo zeenja ezahlukeneyo. Kwezinye iintlobo, ezifana ne-Siberian Husky kunye ne-Alaskan Malamute, amehlo aluhlaza okwesibhakabhaka luphawu olunqwenelekayo oluhambelana namandla okusebenza kunye nobuntu. Kwezinye iintlobo, ezifana neBorder Collie, amehlo aluhlaza akaqhelekanga kwaye anokuthathwa njengesiphoso kwiringi yokubonisa.
Intsomi vs. Inyani: Amehlo aBlue kunye noMoya
Kukho intsomi eqhelekileyo yokuba izinja ezinamehlo aluhlaza zinobundlobongela okanye zinomoya ohlukileyo kunezinja ezinamehlo amdaka. Nangona kunjalo, abukho ubungqina besayensi obuxhasa eli bango. Umbala wamehlo enja awunakunxulumana nobuntu okanye ukuziphatha kwabo.
Ikhonkco phakathi koMbala weMbasa kunye noMbala waMahlo
Kwezinye iintlobo zeenja, kukho ikhonkco phakathi kombala wedyasi kunye nombala wamehlo. Ngokomzekelo, i-merle gene, eyenza ipateni yengubo yebhatyi, inokuchaphazela amehlo, ibangele ukuba ibe luhlaza okwesibhakabhaka okanye inxalenye eluhlaza okwesibhakabhaka. Ezinye iintlobo, ezifana ne-Australian Shepherd, zinokuba nemibala yamehlo eyahlukileyo ngokuxhomekeke kumbala wabo wengubo.
Amehlo aBlue kunye neCrossbreeding
Amehlo aluhlaza anokubakho kwiinja ezixubeneyo ngenxa yokudityaniswa kweentlobo ezahlukeneyo. Nangona amehlo aluhlaza engelophawu oluthembekileyo lohlobo lwenja, anokubonelela ngomkhondo kwinzala yenja.
Yintoni Amehlo Aluhlaza Athetha Ngobuntu Benja
Njengoko kukhankanyiwe ngaphambili, umbala wamehlo enja awunanto yakwenza nobuntu okanye indlela yokuziphatha. Nangona kunjalo, abanye abantu bakholelwa ukuba izinja ezinamehlo aluhlaza zikrelekrele, zizimele, kwaye zinomdla kunezinja ezinamehlo amdaka. Nangona kungekho bungqina besayensi bokuxhasa la mabango, ubuhle bamehlo aluhlaza ngokuqinisekileyo bunokwenza inja ibonakale kwaye ibambe ingqalelo yethu.
Ukukhathalela Inja Yakho Ebomvu-Eyed
Ukuba unenja enamehlo aluhlaza, kubalulekile ukukhathalela ngakumbi amehlo abo. Ukuhlolwa rhoqo kugqirha wezilwanyana kunokunceda ukubona naziphi na iingxaki zamehlo kwangethuba, kwaye kubalulekile ukugcina amehlo enja yakho ecocekile kwaye engenabo ubumdaka. Kufuneka ukhusele namehlo enja yakho elangeni ngokusebenzisa izibuko zelanga ezilungele inja okanye uzigcine emthunzini.
Ukuqukumbela: Ukubhiyozela uBubuhle bezinja ezinamehlo aluhlaza
Ukuqukumbela, amehlo aluhlaza kwizinja luphawu olunomdla kwaye oluhle oluye lwathatha ingqalelo yethu kangangeenkulungwane. Nangona kukho iinkxalabo zempilo ezinxulumene nalo mbala wamehlo, amehlo aluhlaza ngokuqhelekileyo akanabungozi kwaye anokongeza kubuntu obukhethekileyo benja kunye nomtsalane. Nokuba unayo inja yohlobo olusulungekileyo okanye oluxubeneyo enamehlo aluhlaza, kubalulekile ukuxabisa ubuhle babo kwaye ukhathalele amehlo abo.
