Phenotype - uphawu lomzimba okanye iimpembelelo zokusingqongileyo?

Abanye abantu abanomdla umbuzo wokuba yintoni phenotype. Le nkcazelo nga kuthathelwa ingqalelo evela iimbono ezimbini. Ukuthetha yokuzenzisa, lo phenotype - na ukumelwa langaphandle lomzimba, leyo ixhomekeke iseti ezibonisa kweejini. Kokuqwalasela inkcazelo ngokweenkcukacha, singatsho ukuba ezi ezinye iimpawu, aqukiweyo nokulawulwa yemfuza ezithile.

Iimpawu phenotype abayinqobo kuye, ebonakalaliswe abantu ngezigaba ezahlukeneyo zophuhliso. Formation iimpawu ze data kwenzeka phantsi kwempembelelo ezithile imiba yokusingqongileyo kunye kweejini yabantu.

molecule kunye nezakhiwo umzimba ngamnye, nto leyo eyinxalenye ye phenotype ezongeziweyo yaye beminwe yi zofuzo ayikwazi ukubonwa ngohlobo zangaphandle umzimba. Umzekelo, igazi ayifumani ukufumanisa nangaphandle. Ngoko ke, zonke iimpawu phenotype ogqitywe izixhobo ezizodwa, kwakunye neenkqubo zonyango, zokuxilonga kunye nobugcisa.

Phenotype - lelona ukuziphatha kunye abasabela iimpembelelo zokusingqongileyo ukuba lufunyanwa ekuhambeni kwexesha, kuxhomekeke izinto ezithile. Umzekelo, edamini unako kuqwalaselwa beaver phenotype. Ukusuka iintlobo ngentlobo iinkalo ezimbini lweempawu phenotype zingahlukaniswa - le ubuntununtunu kunye multidimensionality. Eyona yokuqala linoxanduva "athathe-out" inkcazelo ethile yemfuza njengempendulo iimeko ezithile zokusingqongileyo. Kwakhona, lo msebenzi osemqoka unoxanduva phenotype weqondo ubukhali izinto ezinjalo. Uphawu leyo kugqiba inani ngqo "ukususa" kolwazi ukusuka yokwahluka gene ukuhlangabezana imiba kwaye sichaza ezo miba leyo ethe ngokukhethekileyo phenotype - into multi-ntathu. Ezi mpawu banoxanduva ubutyebi. Ngamanye amazwi, le yoyilo ngakumbi kunye novakalelo, i ngakumbi le phenotype. Umzekelo, phenotype zabantu kubabetha ngaphezu koko kuzo naziphi na iintsholongwane, ukuze ngaphezulu dimensionality yokuqala azalwa novakalelo.

izidalwa Phenotype zixhomekeke kwizinto ezifana kweejini, imiphumo utshintsho lobume kwaye omzimba random ngenxa wezakhi. Xa kunjalo, ukuba isiphumo into eyodwa phezu kuphawu yeziphumo ngaphezulu kwezinye izinto, ngokulandelelanayo, kunciphisa. Ngokomzekelo, iliso umbala lixhomekeke kweejini, kwaye mawele ukuze umahluko iimpawu ezifana ubude, ekuye kwagqitywa kwimpembelelo yeemeko ezithile zokusingqongileyo. Kwakhona phantsi kweempembelelo imiba yangaphandle bafumane kohlobo isifo C (kweejini 1).

Xa okusingqongileyo kukho ezininzi ngeziganeko, efana phenotype. Le yantlukwano unako ukukhonza njengemfuneko ephambili nasekusungulweni eziphilayo nokusinda zendalo. Ngokomzekelo, pine, nto leyo kwiimeko ezahlukeneyo khangela ezahlukeneyo: ehlathini, ukuba slim, abade, kwaye emasimini kwi ematyeni - ingxobotshane yabanabileyo ngakumbi.
