Combinatorial, Ukwahluka mutational kanye ukuguqulwa

Ukuguqulwa Ukwahluka - siyipropati kakhulu ibalulekileyo eziphilayo ukuqhelana yemeko ezisingqongileyo. Le iseti yendlela, nto leyo ke lithathelwe komzimba ka umzimba okanye wonke labantu ukuba utshintsho iimeko zokusingqongileyo. Ngokomzekelo, isikhumba kwelanga ngaphezulu okanye ngaphantsi mnyama umntu ngamnye.

Ukuguqulwa Ukwahluka kunye neempawu zayo

Le impahla eziphilayo ineempawu uphawu:

• Ukuguqulwa Ukwahluka kuchaphazela kuphela phenotype (iimpawu zangaphandle), kodwa akukho ukusebenza kweejini (yemfuza of an iseti ngamnye).
• Yeyona uhlobo qela - ukuba ezinye iimeko zokusingqongileyo kuchaphazela iqela eziphilayo, ngoko bonke abameli balo waphawula imbonakalo iimpawu ezifanayo.
• Ukuyilungisa - utshintsho kuvela phantsi kwempembelelo rhoqo yeemeko ezithile. Ukuba ukudluliselwa umzimba kwezinye iimeko okanye ukuphelisa isiphumo ezinokuphembelela utshintshe phenotypic shwaka.
• Iinguqu ezenzeka phantsi kweempembelelo iimeko zangaphandle, hayi ilifa.

Kufuneka kuqatshelwe ukuba Ukwahluka ukulungiswa kubaluleke kakhulu ukuba inkqubo yokukhethwa zendalo. Inyaniso yokuba indalo asinde ezo izinto ezizezona ifanele iimeko, ingakumbi utshintsho ngesiquphe xa iimeko zangaphandle. Combinatorial kwaye akukho lula ukumisela mutational ayikho ngokupheleleyo inika umzimba kunye isakhono sobugcisa sokuziqhelanisa.

Ukuguqulwa Ukwahluka: imizekelo

Kwindalo, umntu unako ukufumana imizekelo ingenakubalwa utshintsho olunjalo eziphilayo. Apha ngezantsi kudweliswe ixhaphakileyo.

• Xa ukunyuka ezintabeni, apho ukutshintsha iimeko zokusingqongileyo, egazini labantu okanye isilwanyana yokwanda kwenani iiseli ezibomvu, ivumela unikezelo ioksijini eqhelekileyo.
• Xa baboniswa yelanga eyingozi sabelo iqala kombala zomzimba esikhumbeni.
• Ngenxa yoko, rhoqo olukhulu mass umthambo kwezihlunu inyuswe kakhulu. Emva kokuba kuphela umsebenzi umzimba ngcembe uphelelwa luthambe kunye nezihlunu uyewehla ngokobukhulu.
• Ukuba emhlophe zeHimalaya umvundla lihamba ngokulinganisela iimeko zemozulu kwaye ndawo wazicheba lomzimba, iinwele omtsha iza kuba hina.
• Ukuba imithi sele amagqabi yandiswa ngokupheleleyo, yaye ebusuku baya kuchaphazeleka yi amaqondo obushushu ngezantsi zero, kusasa uya kuqaphela sayingqombela nombala olwahlukileyo.

Ukuze siqonde uhlobo izixhobo kokulungiswa, kubalulekile ukuqwalasela ezinye iintlobo Ukwahluka.

akukho lula ukumisela combinatorial

Ukwahluka olunjalo ngenxa recombination ye zofuzo gametes lweposi. Ngoku khawucinge umzekelo: ukuba umntwana uyise amehlo aluhlaza neenwele mnyama, kunye nomama wakhe - iinwele zigwangqa kunye namehlo aluhlaza. A umntwana azalwe ngendlela amehlo aluhlaza neenwele zimhlophe okanye iinwele ezimnyama kunye namehlo aluhlaza. Kuyinto ezi nguqu phenotypic zibonelelwa Ukwahluka combinatorial nenzala.

akukho lula ukumisela mutational

kuvela utshintsho ukubhentsiswa umzimba mutagens lwekhemikhali, ngokwasemzimbeni okanye uhlobo eziphilayo. Ukwahluka Mutational ngokungafani Uguqulelo kancinane:

• Oku kuvela ngumdla, kwaye kwenzeke ukuba baqikelele;
• Ibangela utshintsho kwi zofuzo;
• utshintsho mutational ukumelana ne ilifa;
• kwezakhi isenokuba ingozi okanye ezidala izifo okanye ukufa;
• ke musa ixhomekeke iimeko zokusingqongileyo;
• kwenzeka abanye abantu;

Njengoko ubona, Ukwahluka - yinkqubo entsonkothileyo kakhulu ukuba lubandakanya kokubini kweejini kunye neempawu phenotype. Kungenxa uguqulelo kancinane, imidibaniso kunye yemfuza zezinto eziphilileyo ngcembe zatshintsha, ukuphucula size sivumelane utshintsho.
