Ukwahluka Phenotypic kunye neempawu zayo

ukwahluka Phenotypic - yinkqubo ebaluleke kakhulu evumela ukukwazi komzimba ukuze asinde. Kuyinto ngenxa yakhe ukuba uyakwazi ukuziqhelanisa neemeko zokusingqongileyo.

Okokuqala ukuguqulwa Ukwahluka eziphilayo sele ubonile izifundo Charles Darwin. Izazinzulu zikholelwa ukuba kungenxa yokuba kukho ukhetho yendalo endle.

ukwahluka Phenotypic kunye neempawu zayo eziphambili

Yinto akukho mfihlelo ngexesha nasekusungulweni izinto eziphilayo atshintsha rhoqo, uvumelane kusinda kwindawo engaphandle. Ukuvela kweentlobo ezintsha yabonelelwa izinto ezininzi - ukutshintsha isakhiwo ilifa izinto (Ukwahluka genotypic), kwakunye ukubonakala iimpawu ezintsha, owenza kokuphilayo iphila xa ukutshintsha iimeko zokusingqongileyo.

ukwahluka Phenotypic inemisebenzi ezininzi:

• Okokuqala, kule fomu abachaphazelekayo kuphela phenotype - iseti iimpawu imbonakalo kunye neempawu omzimba ophilayo. zofuzo akatshintshi. Ngokomzekelo, abantu ezimbini izilwanyana ezihlala kwiindawo ezahlukeneyo, abanye umahluko ngembonakalo, nangona kukho kweejini efanayo.
• Kwelinye icala, Ukwahluka phenotypic Ungumlinganiswa iqela. Utshintsho kwi isakhiwo neempawu zonke izinto zenzeka ngendlela elinabantu elinikiweyo. Thelekisa, kubalulekile esithi ukuba tshintsho kweejini angamanye kunye ezizenzekelayo.
• Ukuguqulwa lula ukumisela ingathityazwa. Ukuba ususe ezo zinto ezithile esamcaphukisayo yokusabela ngomhla ilungu lomzimba, phezu kobuchule kwexesha uya kunyamalala.
• utshintsho Phenotypic akukho ilifa, ngokungafaniyo ukuguqulwa yemfuza.

Ukwahluka Phenotypic kunye nezinga yokusabela

Njengoko sele kukhankanyiwe, utshintsho phenotypic alithethi nayiphi na ukuguqulwa yemfuza. Eyokuqala impembelelo kweejini abasabela ngeemeko zokusingqongileyo. Kulo mzekelo, hayi ngokwakhe iseti yemfuza, kodwa amandla iimpawu zazo.

Kakade ke, olo tshintsho kufuneka imida zabo ezibizwa yokusabela. yokusabela - uluhlu lwazo zonke iindidi ngeendidi apho kunokwenzeka ukhetha kuphela ezo iinketho eziya kuba efanelekileyo data phantsi kweemeko ezithile. Le rate kuxhomekeke kuphela kweejini, kwaye umda zayo eliphezulu nengasezantsi.

ukwahluka Phenotypic kanye ngezigaba yayo

Kakade ke, lo typology of Ukwahluka kubalulekile kakhulu, ekubeni zonke iinkqubo kunye amanqanaba nophuhliso ephilayo nangoku kufundwe ngokupheleleyo. Noko ke, ukulungisa bohlulwa babe ngamaqela, kuxhomekeka kwiimpawu ezithile.

Ukuba uthathe ingqalelo imiqondiso ezitshintshileyo omzimba thina, ukuba kwahlulwa ibe:

• Morphological (imbonakalo basis of umzimba, umz, lexinene umbala uboya).
• Bokuphila (kukho utshintsho ukutya kunye neempawu ukusebenza komzimba okanye ephilayo, ezifana njengomntu, bakhwela iintaba, inani iiseli ezibomvu ukunyuka kakhulu).

Ubude ekude zokulungisa:

• Noninheritable - utshintsho zikhona umntu omnye kuphela okanye labemi, abaye bachaphazeleka ngqo yemeko ezisingqongileyo.
• ukuguqulwa Long-term - uthethe ngazo xa ufumene nezokwamkela inzala ngesondo kwaye igcinwe ukuba izizukulwana ezongezelelweyo 1-3.

Kukho ezinye iintlobo ze isikrokro phenotypic, ezo akasoloko anexabiso esifanayo:

• Ukuguqulwa - ziinguqu ezibangela umzimba ukusebenzisa, ukuziqhelanisa kunye nokubonelela yokusebenza abaqhelekileyo kwi bume.
• Morphosis - ezo utshintsho phenotype, apho kwenzeka phantsi kwempembelelo ndlongondlongo, imiba kakhulu kwezendalo. Apha Ukwahluka iya kude ngaphaya eqhelekileyo yendlela , kwaye ungaze kokufa eziphilayo.
