Rerekētanga Combinative me tona hiranga whanaketanga

Ko te rerekētanga Combinative he take nui o te kanorau intraspecific o kaiao ora katoa. Ko tenei momo o te whakarereke ira arata'i ki te hanganga o ngā hou o āhuatanga kē reira anake. A e kore rerekētanga combinative me ona tikanga kore e meinga te ahua o te ngā ira faufaa rerekē. Ko te putanga o ngā āhuatanga katoa hou e tika ana ki te rerekētanga ira rerekē, ka taea anake i roto i te take o ngā rerekētanga mutational intraspecific.

rerekētanga Combinative whakaritea e te āhua o te tukanga whakaputa uri. Hoki tenei momo o te whakarereke ira ahua āhuatanga o ngā tohuira hou i runga i te pūtake o te ngā ira hou i hanga. faaite rerekētanga Combinative ake kua i roto i te wāhanga o te hanganga o tohuhema (pūtau iroriki). Ano, i roto i te pūtau taua ia kanohi e tetahi anake pūira huirua i ia takirua. Āhuatanga e te meka e taka nga ngā pūira ki pūtau iroriki matapōkeretia, ai kia rerekē tohuhema i roto i te kotahi kaiao kaha nui i runga i te huinga ira. e kore e puta te reira ki te hei i tetahi huringa i roto i te āhua matū o te kawe tika o ngā mōhiohio tuku.

Ko te kupu, rerekētanga combinative he tika ki te momo o te tauhono o ira e kua reira i roto i te huinga pūira. Tenei momo o te whakarereke ira kore hoki e haumi ki huringa i roto i te pūira me te ira hanganga. kia rerekētanga Rauemi combinative te tukanga anake e puta i roto i te whakaiti i wehewehenga pūtau (pūira) me te kikiritanga.

Elementary (iti) kōwae recombinations rerekē rauemi tuku, meinga hanganga o ngā ira hou, ka karanga Recon. Ka hāngai ia Recon ki e rua nucleotides (te rauemi hanga o te waikawa karihi) i roto i te rua-paea rāpoi DNA me te nucleotide kotahi, ina tae mai te reira ki te hanganga o te wheori waikawa karihi kotahi-paea. Ko kore te wehewehe Recon ina whiti (tukanga whakawhiti i waenganui i te takirua pūira huirua i roto i conjugation) me i roto i te wā katoa tuku i roto i te ki tonu i.

rerekētanga Combinative i roto i ngā pūtau eukaryotic i roto i ngā huarahi e toru:

1. tauhononotanga ira i roto i te tukanga o te whakawhitinga-runga, ai e hanga e he i te pūira ngā hou o ngā irarā.
2. purara tupurangi Motuhake o pūira i roto i anaphase o te taahiraa wehenga meiotic tuatahi, ai gamete katoa whiwhi ratou ake ngā āhuatanga ira.
3. Tūao pūtau tūponotanga iroriki i roto i te kikiritanga.

Ko te kupu, e te tikanga o enei tikanga e toru combinative rerekētanga ia kākano pūtau i hanga e te hononga o tohuhema, riro te huinga rawa ahurei o te mōhiohio ā-ira. Nu whakamārama e whakarerekētanga pērā te kanorau nui i roto i ngā momo. He tino nui mo te kukuwhatanga o tetahi momo tauhono ira, rite ki te hanga i te reira i roto i te momo tini o ngā tohuira. homai tenei i tetahi heterogeneity o te taupori. Ko te ahua o kaiao, e hua ana ki ona ake āhuatanga takitahi, whakatau te tōtika tiketike o te kōwhiringa tūturu, hoatu te whai wāhi ki te waiho anake te huinga angitu tino o huru tuku ia ia. Ngā mihi ki te kaporeihana o kaiao hou ki te tukanga whakaputa uri, kei te tonu ake te hanganga ira.
