Amehlo emibala eyahlukileyo

Amehlo enemibala eyahlukileyo ebizwa ngokuba yi- heterochromia . Le ntsho kuthiwa xa amehlo omntu omnye okanye isilwanyana sinombala ohlukileyo we-iris. Umbala we-iris ukhankanywe ngumlinganiselo we-melanin. I-Melanin i-pigment, ngenxa yokuba izinwele zethu, isikhumba kunye namehlo zidaywe. I-Melanin ikhiqizwa kwiiseli ezikhethekileyo ze-melanocytes kwaye yongeza ukukhusela ulusu kwi-ray ultraviolet.

Izizathu zamehlo enemibala eyahlukileyo

Ukuqonda ukuba kutheni kukho amehlo emibala eyahlukileyo, kuyimfuneko ukuqonda indlela umbala wamehlo womntu ngokubanzi uzimisele ngayo. Isigqibo esisisigxina sinesifazana, nangona sibonakala ngokuhlukahlukileyo. Imibala emine esekelwe yimibala eyahlukahlukeneyo yombala kwamehlo kubantu abajikeleze ihlabathi. Ukuba iinqanawa ze-iris zine-blue tint, umnikazi wamehlo anokuziqhayisa nge-blue, blue or gray iris.

Kwimeko yexabiso elaneleyo le-melanin kwi-iris, amehlo aya kuba mnyama okanye awamnyama (anokukhululeka). Imibala ephuzi ivela phambi kwezinto ezinxulumene nokuphulwa kwesibindi. Amehlo abomvu angama-albinos kuphela, abantu abane-melanin. Ukongeza kwamehlo obomvu, aba bantu banesikhumba esiluhlaza kunye neenwele ezingenambala.

Udidi oluhlukeneyo lwemibala engundoqo luhlanganisene nenani elikhulu lamathunzi. Ngokomzekelo, amehlo aluhlaza afunyanwa ngokuxuba obomvu nohlaza okwesibhakabhaka, kunye nokuhlambalaza xa kudibanisa okwesibhakabhaka kunye nomdaka.

I-Heterochromia iphinda ikhule ngexesha lokubeleka, ngenxa yenguqu emva kokuchumisa i-oocyte. Akunakho ukuhamba kunye neziphi izifo ezithintekayo kunye neengxaki. Kodwa kwezinye iimeko, abantu abanamehlo ahlukeneyo banesifo esivela kwizifo ezahlukahlukeneyo kunye ne-syndromes. Okuqhelekileyo kwezi zi- vitiligo , i-Waardenburg syndrome, i-melanosis ye-ocular, i-leukemia, i-melanoma, njl.

Iindidi ze-heterochromia

Iintlobo ze-heterochromy kwindawo:

1. Gcwalisa . Kule meko, abantu banemibala eyahlukileyo yamehlo omabili (enye eluhlaza okwesibhakabhaka, enye i-gray).
2. Candelo . Kule meko, imibala emibini eyahlukileyo iyahlanganiswa kwi-iris enye. Ngokuqhelekileyo umbala omnye uphambili, kwaye okwesibini kuvela kwimvelaphi yayo kwifom yecandelo elincinci.
3. Ephakathi . Olu hlobo lubonakaliswa yimibini emibini okanye emibini, enye yazo ilawula iris yonke, kunye nezinye okanye ezinye zifakwe ngendandatho yomfundi.

Abanikazi bamehlo emibala eyahlukileyo

Inani elincinci elincinci labantu abane-heterochromia liyabonwa emhlabeni jikelele. I-1% yabemi behlabathi ibonakala ingaqhelekanga ngenxa yamehlo ahlukeneyo. Kodwa akukho abantu abanobu bungqina. Ixhaphake phakathi kweekati, apho iso linye lizinzileyo eluhlaza okwesibhakabhaka, kwaye okwesibini lunokuluhlaza okwesibhakabhaka, oluhlaza okanye olwandle. Phakathi kweentlobo zeekati, i-heterochromia idlalwa rhoqo kwi-Angora, Kanye nezinye iintlobo ezinemibala emhlophe yengubo. Phakathi kweenja, i-heterochromia inokuthi ibonakale kwi-Husky yaseSiberia, iBorder Collie, uMalusi wase-Australia. Amahhashi, iibhokhwe kunye neenkomo nazo zinakho i-heterochromia, ezingathinti impilo yazo nayiphi na indlela.

Ngaba ndifuna ukwenza into?

I-Heterochromia ayikuthinteli ngokwenyama kumntu, vumela izilwanyana. Ngomgangatho wombono, akuchaphazeli. Ngokuqhelekileyo, abantu abajongene neengxube zamehlo ezinombala basebenzisa ii-lens zokudibanisa ukulungiswa kwazo. Ngenxa yeempawu zobuntu abanjalo abantu bathiwa bathembeka, bathathaka, bathembeke, bazinike, baxabane kunye ne-egocentrism. Bakufumanisa nzima ukuba bangabikho kwinqanaba lokuqwalasela, kwaye bayakhubaza.
