Genetics - isayensi ngokusondeleyo enxulumene kunye imvelaphi kunye nembali yoluntu. Enyanisweni, kwaba wavumela ukutyhila le nxalenye entsonkothileyo yobomi kwaye thusa kunye eziye zafunyaniswa zayo nanto, umzekelo, ezifana isifundo kwimfuza kunye nezifo chromosomal.

Ukuba ilula kakhulu ukucacisa iinjongo kunye neenjongo kwale nzululwazi, singatsho ukuba izifundo zofuzo uchonge neepatheni yelifa lonke uhlanga lwabantu. Umzekelo, liphonononga iimpawu indlela lwangaphandle (imilo olukhethekeliyo intloko, impumlo, umbala wamehlo, iinwele, kwaye ngaphezulu) kunye nabantu abangaphakathi (ingakumbi umsebenzi kweenkqubo enzyme). Ngaphezu kokuba embindini nasekufundweni yemfuza yindoda, zonke izinto eziphilayo emhlabeni kwakhona ixhomekeke iinkqubo ekuqaleni ibekwe kwinqanaba yemfuza.

intsimi elisemagqabini izazinzulu zophando nangoku inzala usaphila zeentsapho yobukumkani, njengoko imikhwa zomawokhulu, ezosulela uthotho izizukulwana, kwaye kusenokwenzeka ukuba kugweba umntu yelo kwintsapho ethile okanye uhlobo.

Ngoko ke, siyazi ukuba abathwali ulwazi kwezakhi zofuzo, nganye into ethile kwaye linoxanduva inkqubo ethile okanye uphawu lomzimba.

A indima ekhethekileyo udlalwa yi sofuzo, nguye owenza ulwazi yemfuza lomntu, leyo iyahluka phantsi kwempembelelo lomnye - sofuzo lubalaseleyo.

Njengomthetho jikelele, izifo ilifa, ngokusondeleyo "ofihliweyo" sofuzo kwaye ingeyongozi logama nje loo nto ukuhlangabezana wesibini efanayo "abagulayo" sofuzo.

Interesting nto: sofuzo ngazo ngokwayo kwizizukulwana eziliqela mkrozweni mnye, de kube lo ntlanganiso engafunwayo kunye ufuzo isibini.

Umzekelo, i-Habsburg ababekwe Isakhiwo ezizodwa ezahlukeneyo kwemihlathi kunye nemilebe. La magcisa yexesha inyaniso ukubonisa ezi ezinxaxhileyo intsapho eni izidwangube. Xa ukubonakala amalungu ale lobukhosi, umntu uyakwazi ukubona ngokucacileyo iimpawu zabo luphawu: intetho elingqingqwa ophantsi, cheekbones ephosakeleyo, uhlobo olulodwa iinkophe asezantsi, malocclusion. Oku kungenxa yokuba imitshato consanguineous, apho waqonda kwiintlanganiso zofuzo sofuzo.

Oku kusebenza ngemiqondiso zangaphakathi - izifo amafa ukuba lilifa abazali ukuba abantwana.

sofuzo, kodwa kunoko ngenxa yentsebenziswano kwawo efanayo, loo nto ithathwa zizazinzulu njengento esisisongelo emibi kuphuhliso kunye nokuqhubekeka lonke uhlanga lwabantu.

Kukholelwa ukuba esi sifo, ezikhula kwezi meko, ngokufuthi kubabulali. Angakwazi sodidi okanye nkqu imiqathango ngokuba ukonakala kwazo iintlanga, zibangelwa zonke isizathu sokuba, wazenza mntu wumbi phantsi igama "zofuzo sofuzo". Xa ipesenti engaginyisi mathe ukunyuka, inani ngokuqhelekileyo kutshabalala.

Le nkqubo kudla lwenzeka kwi imibutho eyahlukileyo ivaliwe okanye xa kukho utshintsho elibukhali evela kwinani elikhulu kwinzala kwi ukuchuma eziphantsi kakhulu. zofuzo sofuzo kwiimeko ezinjalo kuvela rhoqo ngamaxesha athile. angakwazi izibakala ezaziwayo eluntwini ukususela kumaxesha kokubhalwa kwembali.

Ibangela ngoku inkxalabo ukuthi izakhi isiphako azalise inani labantu. Simele sicinge ukuba baya kuba enesiphako bowaphulaphula aphansi ekuzalweni.

iimpawu zangaphandle nezangaphakathi yomntu kuvela ngenxa yokuba ezendeleyo elifeni lakhe. Yaba iimpawu lubalaseleyo kunye sofuzo. Iqela lesibini zingaquka ukungabi okanye nombala albino, kwaye kokushenxa imibala okanye umbala ubumfama, kubazali bakhe, yimpandla amabhinqa abangevayo-mutism, ezimbi RH. Umdla kukuba imibala ilifa matrilineal, kunye nabafazi ngokwabo kunqabile ubunzima kwesi sifo.

Phakathi sex wamhle, ezi mpawu sofuzo ixhaphake kuphela ngo-0.5% yamatyala, ngoxa abantu imibala ixhaphake kakhulu-8% yamatyala.
