I-Abinism yisifo sofuzo esingazibonakalisa ezilwaneni kodwa nasezitshalweni. Ngendlela efanayo umuntu we-albino okufanele athathe ngayo izinyathelo zokuzivikela, isitshalo kufanele senze okufanayo kodwa ... kuye izinto ziyinkimbinkimbi kakhulu.
Njengoba sazi, kwalasha ukungabikho kwezingulube. Uma lokhu kwenzeka ezinhlotsheni zezitshalo, impilo yaso isengozini enkulu, ngoba i-pigment engenayo i-chlorophyll futhi ngaphandle kwayo ayikwazi ukwenza i-photosynthesize futhi, ngakho-ke, yondla noma ikhule. Kepha, I-albinism izithinta kanjani izitshalo ngqo?
Yini i-albinism?
Kwalasha kuyinto a ukuphazamiseka kwezakhi zofuzo okuvela njengomphumela wokushoda kokuhlanganiswa kwama-tyrosinase, okungama-enzyme abhekene nokwakhiwa kwe-melanin kuma-melanocyte, angamaseli e-pigment. Singavela kunoma yisiphi isidalwa esiphilayo, kungaba yisitshalo noma isilwane (kufaka phakathi abantu), futhi kungenzeka nokuthi, ngokwesibonelo, isitshalo sinohlobo lofuzo lwe-albinism olungazibonakalisi kuso kepha olwenza kwezinye zazo inzalo.
Zingaphila izitshalo ze-albino?
Ngeshwa, akukho kuningi. Njengoba bengenayo i-chlorophyll, abakwazi ukuguqula amandla elanga abe ukudla, ngakho-ke ikusasa labo libhalwa ngokushesha nje lapho imbewu ihluma. Akuvamile ukuthi iphile ngaphezu kwezinsuku noma amasonto ambalwa. Kepha… kukhona okuhlukile: i-albino sequoia. Yisixuku, ngokungafani nodadewabo, esimhlophe qwa. Ayikwazi ukufinyelela kumamitha ayi-100, kepha ifinyelela kuma-20.
Kuthiwa lokho ebusuku kukhanya kancane ekukhanyeni kwenyanga, eliyinikeze igama lesipoki redwood. Into enelukuluku ngakho konke lokhu ukuthi kutholakele izinhlobo ezedlula ikhulu lempilo. Kungenzeka kanjani?
Ngokusobala, zanda ngama-propagules - iziqu ezingaphansi komhlaba. Kuqhuma abantu abasha kubo bondla izimpande impilo abazinika zona, baziphathe ngale ndlela njengezinambuzane zabandulelayo.
Uma ufuna ukuyobabona, kuzofanele uye lapho kukhona khona ukuhlushwa okukhulu kakhulu: UHenry Cowell State Park, eCalifornia, noma ubheke le vidiyo:
Ubuwazi umcimbi wakwalasha ezitshalweni?
