Maso Blue - Chifukwa cha kusintha kwa

Asayansi simunamalizebe amati kusintha zinachitika, ndipo panali munthu maso a buluu, koma zizindikiro zina zikusonyeza kuti, osalephera, izo zinachitika zaka zingapo zapitazo. Nthawi imeneyi, panali misa kulamulira ku Ulaya, monga ulimi mu Middle East anayamba kufalitsa mu Europe.

magwero

Journal of Human chibadwa asayansi anaika cholembedwa kuti kusintha, chimene chinapangitsa maonekedwe a maso a buluu mitundu, zambiri zinachitika mu kumpoto chakumadzulo kwa dera Black Sea.

Professor Eiberg anali ananena kuti "kusakhulupirika" mtundu maso athu ayenera kukhala bulauni. Mdima maso a buluu - chifukwa cha kusintha, chifukwa mdima khungu pigment - melanin, zimakhudza maonekedwe a ana bulauni-eyed anabadwa. Komabe, kumpoto kwa Ulaya OCA2 jini anakumana kusintha kusokoneza yopanga melanin mu Iris, amene kwachititsa kuti maonekedwe a mtundu wa buluu.

Professor Eiberg ananena kuti maso bulauni anali woyamba wa zonse, koma masinthidwe DNA wathu OCA2 jini anapangitsa "kusintha" kuti "zimitsani" luso la anthu kutulutsa mtundu bulauni.

The Iris zimasiyanasiyana kuchuluka kwa melanin, ndi mitundu Choncho osiyana bulauni. maso Blue anthu amene kholo lawo ndi limodzi amene anasintha mbewu. Onse a iwo analandira kusintha chomwecho mu DNA awo.

amuna maso a buluu ndi akazi pafupifupi zofanana majini ndondomeko ya mbali ya DNA, amene ali ndi udindo kwa diso mtundu.

Professor Eiberg kunachitidwa DNA kusanthula anthu oposa 800 kuchokera woyera khungu Scandinavia lagolide kwa anthu khungu loderapo, koma ndi maso a buluu, tikukhala mu Turkey ndi Jordan. kuyesera wake anatsimikizira kungoganizira umodzi kholo limodzi.

Ndi bwinobwino chifukwa buluu maso kwambiri ofala anthu ambiri a South la Russia ndi kumpoto Europe. Poyamba anali ankaganiza kuti mbali amapereka mwai m'chilimwe usiku dzuwa kapena yozizira kumalo ozizira. Mwina izi amaona kukhala wokongola kwambiri, choncho ndi yabwino kwambiri kusankha kugonana.

Features

Anatomically Iris zikuphatikizapo ectodermal ndi mesodermal wosanjikiza. Pa momwe mukufuna kugawira iwo pigment ndi zimadalira mtundu. Chromatophores amafalitsidwa mu mesodermal wosanjikiza, iwo ali melanin. The backsheet limapangidwa ndi maselo ambiri inki wodzazidwa fustsinom. Kumathandiza monga ulusi ndi Iris ziwiya.

Kiyi kuwala mitundu - buluu, wabuluu, imvi.

Ectodermal wosanjikiza chibadidwe mdima mtundu buluu. Ngati ulusi kunja Iris ali ndi osalimba otsika ndi okhutira otsika melanin, kuwala mkulu pafupipafupi imatsala mesodermal wosanjikiza ndi otsika kuwala pafupipafupi zimaonekera kwa izo. maso Blue - zotsatirapo za index izi.

Pali anthu amene ndimalota kusintha mtundu wanu achilengedwe buluu. Iwo amakhulupirira kuti view nthawi yomweyo kupeza kukongola, kuya ndi kuchuluka. Nthawi zambiri amatanthauza wokongola maso a buluu chithunzi maso a buluu anthu akhoza azikongoletsa ntchito ena mapulogalamu, monga Photoshop. Pambuyo kwambiri ndi zotsatira kompyuta, inu mukhoza kutenga kunja zodzoladzola lolondola ndi zodzoladzola.
