Amehlo enemibala ehlukene

Amehlo enemibala ehlukahlukene ebizwa nge- heterochromia ngokwesayensi. Lokhu kwenzeka lapho amehlo amabili kumuntu oyedwa noma ngesilwane enombala ohlukile we-iris. Umbala we-iris unqunywa inani le-melanin. I-Melanin iyi-pigment, ngenxa yokuthi izinwele zethu, isikhumba namehlo zidaywe. I-Melanin ikhiqizwa emangqamuzaneni akhethekile ama-melanocyte futhi ngaphezu kwalokho ivikela isikhumba emisebeni ye-ultraviolet.

Izimbangela zamehlo emibala ehlukene

Ukuze uqonde ukuthi kungani kukhona amehlo emibala ehlukene, kubalulekile ukuqonda ukuthi umbala weso lomuntu uvunyelwe kanjani. Isici esiqakathekileko sinesifazana, nakuba sibonakala ngokuhlukahluka okuhlukahlukene. Imibala emine eyisisekelo yenza izinhlobo ezihlukahlukene zombala wombala kubantu emhlabeni jikelele. Uma izitsha ze-iris zinama-bluish, khona-ke umnini wamehlo anjalo angaziqhayisa nge-blue, blue or gray iris.

Uma kwenzeka inani elanele le-melanin e-iris, amehlo azoba nsundu noma ngisho amnyama (ane-overabundance). Ama-shadow shades ayenzeka lapho kukhona izinto ezihlobene nokuphulwa kwesibindi. Amehlo abomvu angama-albinos kuphela, abantu abane-melanin. Ngaphandle kwamehlo abomvu, laba bantu banekhanda eliphaphathekile nezinwele ezingenambala.

Inhlanganisela ehlukene yemibala eyisisekelo ihlanganisa inombolo enkulu yama-shadow. Isibonelo, amehlo aluhlaza atholakala ngokuxuba okwesibhakabhaka nohlaza okwesibhakabhaka, futhi ahlambalaza lapho exubha okwesibhakabhaka enosundu.

I-Heterochromia nayo iqala ngesikhathi sokubeletha, ngenxa yokuguqulwa komzimba emva kokukhulelwa kwe-oocyte. Kungenzeka ukuthi ihambisane nanoma iziphi izifo ezixhumene nezifo. Kodwa kwezinye izimo, abantu abanamehlo ahlukene nabo bahlushwa izifo ezihlukahlukene kanye nezifo ezihlukahlukene. Okuvame kakhulu kulawa yi- vitiligo , i-Waardenburg syndrome, i-melanosis ye-ocular, i-leukemia, i-melanoma, njll.

Izinhlobo ze-heterochromia

Izinhlobo ze-heterochromy ngendawo:

1. Qedela . Kulesi simo, abantu banemibala ehlukene yamehlo womabili (eyodwa eluhlaza okwesibhakabhaka, enye eyimpunga).
2. Sectoral . Kulokhu, imibala emibili ehlukene ihlangene ku-iris eyodwa. Ngokujwayelekile umbala owodwa ukhululekile, kanti owesibili usezindaweni zangasese ngesimo sesigaba esincane.
3. Ephakathi . Lolu hlobo lubonakala ngemibala emibili noma ngaphezulu, enye yayo ilawula iris yonke, kanti enye noma ezinye zihlelwe yindandatho yomfundi.

Abanikazi bamehlo ngemibala ehlukene

Inani elincane elinelisiwe labantu abane-heterochromia liyabonakala emhlabeni jikelele. Cishe u-1% wabantu bezwe abukeka engavamile ngenxa yamehlo ahlukene. Kodwa akukhona nje abantu abanobu buhle. Ixhaphake phakathi kwamakati, lapho iso elilodwa lizinzile oluhlaza okwesibhakabhaka, kanti okwesibili kungaba ophuzi, oluhlaza noma olulintshi. Phakathi kwezinhlobo zamakati, i-heterochromia ivame ukubhekwa emlandweni we-Angora, Kanye neminye imikhakha embala womhlophe omhlophe. Phakathi kwezinja, i-heterochromia ingabonakala ku-Husky yaseSiberia, i-Border Collie, i-Australia Shepherd. Amahhashi, izinambuzane nezinkomo nazo zingaba ne-heterochromia, engathinti impilo yabo nganoma iyiphi indlela.

Ngidinga ukwenza okuthile?

I-Heterochromia ayithwali noma yimuphi umuntu ongathandeki ngokomzimba, ungabi yizilwane. Ngekhwalithi yombono, futhi ayithinti. Ngokuvamile, abantu ababhekene nezinkathazo zamehlo ezinemibala basebenzise ama-lens wokuxhumana ukuze balungise ukubonakala kwabo. Ngaphandle kwezimfanelo zomuntu ezinjalo abantu babalwa ngokuthembeka, ubuncipheko, ukwethembeka, ukuphana, ukuphikisana kanye nokunye okwenziwe yi-egocentrism. Bakuthola kunzima ukuthi bangaba phakathi nendawo, futhi bayamcasula.
