Blue maziso - migumisiro mutation

Masayendisiti ave asi kukarakadza kuti mutation yakaitika, uye makanga murume maziso ebhuruu, asi vamwe zviratidzo zvinoratidza kuti, Ungangove, zvakaitika Mumakumi emakore apfuura. Panguva iyi, kwaiva vakawanda Colonisation kuti Europe, sezvo kurima kuMiddle East akatanga kuparadzira muEurope.

Journal of Human genetics masayendisiti akaisa katsamba kuti mutation, izvo zvakakonzera pakuonekwa meso rwebhuruu hues, Ungangove kwakaitika kuchamhembe kwakadziva kumadokero kweGungwa Dema nharaunda.

Professor Eiberg akanga ambopupura kuti "default" ruvara maziso evanhu zvinofanira kuva shava. Dark zvitema maziso - mugumisiro mutation, nekuti rima ganda ruvara - rwe-melanin, kunokanganisa pakuonekwa shava takangwaririra vanoberekwa. Zvisinei, muna Northern Europe OCA2 Gene ndavhiyiwa kuchinja kuvhiringidza kugadzirwa rwe-melanin ari Iris, izvo zvakakonzera nechitarisiko yebhuruu ruvara.

Professor Eiberg akati kuti maziso shava akanga pakutanga kwezvose, asi kuno- mu okutodza dzedu OCA2 Gene vakatadzisa "kuchinja" kuti "kudzima" mano vanhu kuti pave mashava ruvara.

The Iris dzinosiyana uwandu rwe-melanin, uye naizvozvo zvakasiyana mashava hues. Meso Blue ndivo vanhu vane tateguru uyo akachinja Gene. Vose nhaka chete mutation ravo DNA.

Blue takangwaririra varume nevakadzi vane anenge kufanana nemagene kutevedzana ari chikamu morekuru reDNA, riri basa ziso ruvara.

Professor Eiberg chaiitirwa DNA kuongorora vanhu vanopfuura 800 kubva chena-ganda Air blond kune rima-ganda vanhu, asi nebhuruu maziso, vaigara Turkey uye Jordan. kuedza kwake akasimbisa pfungwa imwe chete kuzitateguru.

Hazvina kujeka nei yebhuruu maziso zvikuru kwakapararira pakati Vagari rwezasi Russia uye Northern Europe. Kare zvakanzi vaifungidzira kuti chikamu ichi anopa mumwe mukana muzhizha pakati pousiku zuva kana polar chando. Zvichida ichi anonzi kuva anokwezva uye, naizvozvo, kupfuura akanakira pabonde vakasarudzwa.

Features

Anatomically Iris zvinosanganisira ectodermal uye mesodermal rukoko. On sei kuparadzira kwavari ruvara uye zvinoenderana ruvara. Chromatophores anoparadzirwa munyika mesodermal layer dzine rwe-melanin. The backsheet unotora pigmented masero akawanda akazara fustsinom. Nezvaanoita sezvo fibers uye iris nemidziyo.

Key chiedza mavara - zvitema, zvitema uye pfumbu.

Ectodermal rukoko kuri mumashoko murima yebhuruu ruvara. Kana kwokunze fibers zviri Iris vane pasi arambe achirema uye pasi zviri rwe-melanin, muprista kakawanda chiedza wefodya mesodermal rukoko uye pasi kakawanda chiedza zvinoratidzwa nawo. Blue maziso - migumisiro indekisi ichi.

Kune vanhu hope kuchinja kwako dzinongoitika ruvara kuti rwebhuruu. Vanodavira kuti maonero panguva kuwedzerwa runako, kudzika uye kukwana. Most rinowanzotaura kuti maziso ebhuruu chinokwezva fungidzira yebhuruu takangwaririra vanhu vanogona shongedza kushandisa zvimwe zvirongwa, akadai Photoshop. Pashure kuedza kombiyuta zvinokonzerwa, unogona sanangurai yakarurama masikirwo uye zvizoro.
