Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: Ka puta te kunenga i roto i ngā rauropi mā ngā huringa i roto i ngā āhuatanga tuku iho - ngā āhuatanga tuku iho o tētahi rauropi. I roto i te tangata, hei tauira, ko te tae o te kanohi he āhuatanga tuku iho, a, ka riro pea i te tangata te "tuhinga kanohi parauri" mai i tetahi o o raatau matua. Ko ngā āhuatanga tuku iho e whakahaeretia ana e ngā ira, ā, ko te huinga katoa o ngā ira i roto i te huinga ira o te rauropi (rauropi iranga) e kiia ana ko tōna momoira. Ko te huinga katoa o ngā āhuatanga e kitea ana e hanga ana i te hanganga me te whanonga o te rauropi e kiia ana ko tōna tohuāhua. Ko ēnei āhuatanga e ahu mai ana i te pāhekoheko o tōna momo ira ki te taiao. Ko te hua, he maha nga āhuatanga o te momo āhuahanga o te rauropi kaore i te tuku iho. Hei tauira, ko te kiri whero ka puta mai i te tauwhitinga i waenganui i te momo ira tangata me te marama o te ra; nō reira, kāore ngā whero e tukuna atu ki ngā tamariki o te tangata. Heoi, ko ētahi tāngata he māmā ake i ētahi atu, nā ngā rerekētanga i roto i te rerekētanga genotypic; he tauira whakaharahara ko te iwi ki te āhuatanga tuku iho o te albinism, e kore e tan i te katoa, me te he tino tairongo ki te sunburn. Ka whakawhitihia ngā āhuatanga tuku iho i tētahi whakatupuranga ki te whai ake mā te DNA, he rāpoi ngota e whakaraupapa ana i ngā mōhiohio iranga. Ko te DNA he pūtaiao roa e whā ngā momo pūtake. Ko te raupapa o ngā turanga i te rāpoi DNA motuhake e tohu ana i te mōhiohio iranga, i runga i te āhua rite ki te raupapa o ngā reta e tohu ana i tētahi rerenga kōrero. I mua i te wehenga o te pūtau, ka tāruatia te DNA, kia whiwhi ai ia pūtau e rua i te raupapa DNA. Ko ngā wāhanga o te rāpoi ngota DNA e tohu ana i tētahi wae mahi kotahi, e kiia ana ko ngā ira; he rerekē ngā raupapa pūtake o ngā ira rerekē. I roto i ngā pūtau, ko ngā aho roa o te DNA e hanga ana i ngā hanganga kōpeke e kiia nei ko ngā chromosomes. Ko te tauwāhi motuhake o tētahi raupapa DNA i roto i tētahi chromosome e mōhiotia ana he wāhi. Mēnā he rerekē te raupapa DNA i tētahi tauwāhi i waenganui i ngā tāngata, ka kīia ngā momo rerekē o tēnei raupapa ko ngā ira. Ka taea e ngā raupapa DNA te huri mā ngā irakētanga, e whakaputa ana i ngā ira hou. Mēnā ka puta he irakētanga i roto i tētahi ira, ka pā te ira hou ki te āhuatanga e...  Pātai: I tehea wā ka tāruatia te DNA e pā ana ki te wehenga pūtau?
