I-Abinism sisifo semfuza esinokuzibonakalisa kwizilwanyana kodwa nakwizityalo. Ngendlela efanayo naleyo umntu we-albino kufuneka athathe amanyathelo okuzikhusela ngayo, isityalo kufuneka senze njalo kodwa ... kwimeko yakhe izinto zinzima kakhulu.
Njengoko sisazi, enzonzobileni - ukungabikho zombala. Xa oku kusenzeka kuhlobo lwesityalo, ubomi baso busengozini enkulu, kuba i-pigment engenayo yi-chlorophyll kwaye ngaphandle kwayo ayikwazi ukwenza i-photosynthesize kwaye, ke ngoko, yondla okanye ikhule. Kodwa, I-albinism izichaphazela njani izityalo ngokuchanekileyo?
Yintoni ialbinism?
Enzonzobileni yi Ingxaki yemfuza ebonakala njengesiphumo sokusilela kunxibelelwano lwe-tyrosinases, Ezizii-enzymes ezinoxanduva lokwenziwa kwe-melanin kwii-melanocytes, ezizizakhi ze-pigment. Isenokubonakala nakowuphi na umntu ophilayo, nokuba sisityalo okanye isilwanyana (kubandakanywa nabantu), kwaye inokwenzeka nokuba, umzekelo, isityalo sinofuzo olunoxanduva lwealbinism esingazibonakalisiyo kuso kodwa esizibonakalisayo kwezinye inzala.
Ngaba zingaphila izityalo zealbino?
Ngelishwa hayi kakhulu. Ngenxa yokunqongophala kwekhlorofili, abakwazi ukuguqula amandla elanga abe kukutya, ngenxa yoko ikamva labo libhalwa kwakamsinya nje ukuba imbewu ihlume. Ayidla ngokuhlala ngaphezulu kweentsuku okanye iiveki ezimbalwa. Kodwa… kukho okwahlukileyo: ialbino sequoia. Yikhoniferi, ngokungafaniyo noodade wayo, emhlophe ngokupheleleyo. Ayikwazi ukufikelela kwiimitha ezili-100, kodwa ifikelela kuma-20.
Kuyatshiwo oko ebusuku kukhanya kancinane ngokukhanya kwenyanga, Eyinike igama lesiporho redwood. Into enomdla ngayo yonke le nto kukuba iisampulu ezigqithile kwinkulungwane yobomi zifunyenwe. Inokwenzeka njani loo nto?
Kuyabonakala ukuba, zanda nge-propagules - iziqu zangaphantsi komhlaba. Kuvela abantu abatsha kubo batya iingcambu abazinikwe bubomi, baziphathe ngale ndlela ngathi zizidleleli zabaphambili babo.
Ukuba ufuna ukuya kubabona, kuya kufuneka uye apho kukho uxinzelelo olukhulu: I-Henry Cowell State Park, California, okanye jonga le vidiyo:
Ngaba uyayazi inzonzobila enzonzobila kwizityalo?
