Allelic me ira kore-allelic

uara iranga

Ki te kitea o turanga ira o kua riro pūtaiao whānui tïpako turanga rangahau hou o te kukuwhatanga - te waehere ira. E whakatakotoria ana te mōhiohio e pā ana ki ngā rerekētanga o mua, me te ū mai katoa ki te whanaketanga o te rauropi.

whakapapa me te ōwehenga rerekētanga taea ki a koe te whakaora i te kounga pai anake, engari hei utu mo rahua ki te whiwhi te hunga hou, te whakapai ake i te hanganga me te whai wāhi ki te wikitoria i roto i te kōwhiringa tūturu.

ariā Basic o iranga

I roto i te pūtake ira hou mō te pūira kainga whakaae ariā e te tïpako matua ko te pūira morphological - te hanganga o te matatini DNA CONDENSED (pūpūira) i nei i roto i te kōtuitui o te pūmua, me te pānui i ngā mōhiohio.

Genetics i runga i te maha o ngā ariā: te ira (he waehere DNA wāhanga mo te wae āhuatanga motuhake), tohuira me te tohuāhua (huinga o ira me mau huru o te kaiao), tohuhema (pūtau iroriki ki te huinga kotahi o pūira) me whakatō kākano (ngā pūtau diploid).

Ira, i roto i te tahuri, kua whakarōpūtia ki te ngoi (A) me te ngoikore (te) i runga i te nuinga o te āhuatanga tetahi i runga i tetahi allelic (A me te) me kore-allelic ira (A me B) rānei. Allelic kei i runga i te rohe pūira taua, me te Tapa kotahi tohu. Kei ira Non-allelic e tino whakahē ki a ratou i ngā pae rerekē me whakawaehere āhuatanga rerekē. Heoi, ahakoa tenei, i nga ira kore-allelic i te kaha ki te taunekeneke ki a rātou anō, hoatu ara ki te whanaketanga o ngā āhuatanga katoa hou. E ai ki te hanganga kounga o ngā irarā kaiao taea te wehea ki tai'ata e iraruakē ranei i roto i te take tuatahi ko te taua ira (AA, aa), i roto i te tahi atu - he rerekē (Aa).

Tikanga me taunekeneke ira ara iahiko

Forms ira taunekeneke i waenganui i te geneticist American ako T.H.Morgan. Ko te hua o tona rangahau, kua kī ia i roto i te ariā pūira o whakapapa. E ai ki a ia ira ngā i roto i te kotahi pūira e riro tahi. E huaina taua ira hono ka hanga he pera-ka karanga rōpū hononga. I roto i te tahuri, i roto i enei rōpū hoki puta i ira tauhono crossover - pūira whakawhiti tahi ngā wahi. I roto i tenei tino arorau, me te e kï e te meka e kua whakaritea nga ira tika tetahi i muri i te tahi atu, wehenga i roto i te tukanga o te whakawhitinga-mo e kore e whai wāhi me kua riro tahi.

Ki te reira te mea he tawhiti i waenganui i te ira, te tūponotanga o te wehenga vai - ka karanga i tenei āhuatanga ko "ira adhesion pahara." Korero i te reira i roto i te taipitopito atu, te pāhekoheko i waenganui i te ira allelic puta i roto i kaupapa ohie e toru: mana oti ki te hoatu i te huaira ngoi parakore, ngoi pahara ki te hoatu āhuatanga kodominirovanie takawaenga me ki te kainga tupu o huru e rua. E riro ana hoki ira Non-allelic nui uaua: te kaupapa o kïnakitanga, waerau epistasis ranei. Ka Here e riro āhuatanga e rua, engari ki te whānuitanga rerekē.
