Dzinza rako - sayenzi kuti hwakada chokuita mavambo uye nhoroondo yevanhu. Kutaura zvazviri, aiva iye akabvumira kuratidza kupfuura oma muupenyu uye achiri kunoshamisa wayo sanzwisisika zvakawanwa Somuenzaniso, dzakadai kudzidza yedzinza uye chromosomal zvirwere.

Kana zviri nyore chaizvo kuti kutsanangura Zvinangwa nemasayendisiti ichi, tinogona kutaura kuti genetics zvidzidzo uye kuziva mifananidzo nhaka rwevanhu. Somuenzaniso, rinoongorora sei zvimwewo zviratidzo (chaiyo Maumbirwe musoro, mhuno, ziso ruvara, bvudzi, uye zvakawanda) uye dzimwe (kunyanya basa enzayemu hurongwa). Kuwedzera pakuva pakati pakudzidza genetics munhu, zvose zvipenyu panyika zvakare novimba kwemasayendisiti kuti pakutanga akaiswa majini chechetere.

Excellent munda yokutsvakurudza vasayendisiti vachiri vapenyu vazukuru mhuri youmambo, sezvo unhu madzitateguru, kuburikidza dzakatevedzana kumarudzi, uye zvinokwanisika kutonga munhu kunofanira kunyanya mhuri kana genus.

Saka, tinoziva kuti mutakuri masero mashoko vari majini, mumwe nomumwe iri chaiyo uye iri basa chairo mutoo kana chiratidzo muviri.

A rinokosha iri kuridzwa ne recessive Gene, ndiye anotakura majini mashoko munhu, izvo zvichisiyana pasi pokudzora mumwe - chikuru Gene.

Kazhinji, nhaka zvirwere, akanyatsotevera "encrypted" recessive Gene uye havana ngozi chero hazvina kusangana wechipiri chete "sick" recessive Gene.

Interesting chokwadi: asi recessive Gene kungazviratidza kumarudzi akawanda panhurikidzwa kusvikira pane musangano uyu pasingadiwi chete vaviri genome.

Somuenzaniso, mashoko Habsburg youmambo vatongi siyana chaiyo nemamiriro shaya nemiromo. The vemifananidzo nguva zvechokwadi kuratidza zvarakasiya izvi pamusoro mhuri ZVAKAITIKA vanokudzwa. In pakuonekwa nhengo youmambo ichi, mumwe anogona kunyatsoona dzavo nedzevamwe zvinhu: gobvu yakaderera muromo, cheekbones zvakaipa, rinokosha ezasi anopenya, malocclusion. Ichi Pamusana consanguineous dzimba, apo akaziva misangano recessive magene.

Izvi zvinoshandawo dzomunyika zviratidzo - nhaka nezvirwere kuti kubva kuvabereki kuenda kuvana.

Recessive Gene, asi mugumisiro nekuita waro zvakafanana, riri kuonekwa nemasayendisiti sezvo nengozi kuti kukura uye kuenderera rwevanhu.

Zvinofungidzirwa kuti chirwere, izvo kuva muzviitiko izvi, kazhinji zvichiita rufu. Degeneration of genus kana kunyange preconditions nokuda degeneration marudzi, kwakakonzerwa yose chikonzero nei, yakazonyorwa pasi zita "majini recessive". Kana chikamu muzana inowedzerawo kuti yakaoma pakusava, vagari kazhinji kuparara.

Izvi zvinowanzoda nzvimbo yoga namahwindo munzanga kana apo pane unopinza achichinja kubva vazhinji vevana vari pasi kwazvo kubereka. Recessive majini Pakadaro dzinooneka kakawanda dzimwe nguva. degeneration chokwadi anozivikanwa vanhu kubva prehistoric nguva.

Chinokonzera pari hanya kuti majini kuremadza nekuzadzisa kwevanhu. Tinogona kufunga kuti achava chose chakaremara yakaderera pakuberekwa prices.

External uye munyika zvinoratidza munhu somunhu nemhaka yokuti kuri panhaka yake. Govera rave uye recessive unhu. Boka rechipiri zvingasanganisira kusavapo kwakakwana kana pigmentation albinism, uye kutsauka zvakadai ruvara upofu kana ruvara upofu, hemophilia, nemhanza vakadzi matsi-mutism, akaipa kusapindirana kweropa. Interesting ndechokuti ruvara upofu nhaka matrilineal, pamwe nevakadzi pachavo Kashoma vanotambura nechirwere ichi.

Pakati naka pabonde, recessive unhu izvi chete dzakakurumbira 0.5% kubva nguva apo vanhu ruvara upofu zvakawanda zvakajairika 8% nyaya.
