Ukuhlonza ezihlukile abantu zenye: ubufakazi futhi ucwaningo

Ukuhlonza ezihlukile abantu zenye zivunyelwe ukuba zithathe isinyathelo esibalulekile ekuthuthukiseni imfundiso yokuziphendukela kwemvelo. Umqondo futhi Inani lale impahla lithathelwe kuzoxoxwa ngakho esihlokweni sethu.

Uyini kokuhlukana

Ngaphansi kokuhlukana ukuqonda nekhono eziphilayo ukuthola izici ezintsha futhi izakhiwo inqubo yentuthuko ngabanye kanye zomlando. Le mpahla - umphumela lithathelwe yabo imvelo. Ngakho, kokuhlukana e ngabanye zohlobo olulodwa, elibonisa izibonelo ngezansi, okwaholela ukuvela izinhlanga womuntu. SiGaba emincane amehlo mongoloid nesikhumba ophuzi kwakhiwa futhi fixed genotype zabantu abahlala emaqeleni Asian, lapho njalo uthule imimoya enamandla anesihlabathi. A black lesikhumba yi Negroid ka ukuphila ogwadule Afrika.

kokuhlukana izinhlobo

kokuhlukana ekuhlonzeni abantu zenye selukhombisile ukuthi izici ezintsha ayikwazi ngofuzo. Lokhu kungase kutholakale ngokuhamba isilingo. Laboratory amagundane imisila usike bese ewela bodwa. Abantu abanjalo njalo ozalwa nezingane Tailed. Lokhu kokuhlukana ibizwa ngokuthi non-ngofuzo noma ukuguqulwa. Uma izimpawu ezintsha ezithinta apharathasi zofuzo, ukuyishintsha ezingeni elithile, kokuhlukana omkhulu sitholwa njengefa.

ukuguqulwa kokuhlukana

Khumbula imfumbe yezingane: "Ebusika, zibe mhlophe futhi grey ehlobo?" Lona ukuhlonza ezihlukile abantu zohlobo olulodwa. Ososayensi baye babonisa ukuthi isiginali ukushintsha uvolo umbala unogwaja akuyona lokushisa emoyeni, kanye nenani elangeni. Kulula ukufakazela. Uma kuwukuthi inkathi efudumele mnyama yezinyoni noma aviary ne onogwaja, ngemva kwesikhathi esithile, base 'sigqoke amajazi ezimhlophe. "

Ukuguqulwa kokuhlukana phakathi abantu elilodwa zezintaka isitshalo kungenziwa kubhekwe njengento isibonelo ikhanda lomcibisholo. Sikhula emanzini. Amahlamvu zalesi sitshalo, engaphansi kwamanzi, abe ukuma iribhoni-like, phezu kwawo - umcibisholo. Ukushintsha izimo zemvelo kuholela ukuguqulwa isimo sabo. Uma wonke sitshalo ngaphansi kwamanzi, onke amaqabunga athathe isimo tape.

Hhayi kungenzeka zonke izici washintsha ngaphansi kwethonya zezemvelo. Ngokwesibonelo, umbala kwesikhumba kungashintshwa ngaphansi kwethonya emisebeni yelanga. Kodwa on the lwegazi alithintwa yinoma yimuphi izimo. Lesi sici, njengabanye abaningi, sitholwa njengefa.

ukushintshashintsha zofuzo

Izinguquko ezithinta apharathasi zofuzo, kukhona sitholwa njengefa. Abanaso incike izimo zemvelo okubangelwa recombination zezakhi zofuzo noma ukuguquka kwezakhi zofuzo. sici wabo okungahleliwe futhi okungezona ohlangothini ngokwemvelo. kokuhlukana ekuhlonzeni abantu zenye eziphilayo ezihlobene eduze yinto N. I. Vavilova Ucwaningo usosayensi odumile. yi Babephokophele umthetho we chungechunge homologous. essence yayo itholakala iqiniso ukuthi izinguquko eyifa kuyagcinwa e ezinye izilwane, kodwa lungatholwa kwabanye abaseduze naye ngokuzalwa. Ngokwesibonelo, ubu-albino ejwayelekile abameleli babo bonke amakilasi yezilwane ezinomgogodla. Lokhu kuguquka yenteka izinhlanzi nezilwane ezincelisayo.

Ngakho, izinto eziphilayo angaba khona ngeendlela ezihlukeneko. Le mpahla libizwa simo esishubile. Kungaba ezimbili zama. Ukuguqulwa incike izimo zokuphila kwabantu kuvikelwe ku genotype. ukushintshashintsha bofuzo ahlobene nezinguquko asendabeni sitholwa njengefa. Lezi zici ziyadlula ezizukulwaneni. Simo esishubile kuyisici esibalulekile e ukuvela ezincwadini kwemvelo nokunye kugucuka.
