Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: Ko te phenotype o te rauropi takitahi ka puta mai i tana momo ira me te awe mai i te taiao i noho ai ia. Ko tētahi wāhanga nui o te rerekētanga phenotypic i roto i tētahi iwi whānui, he mea take i te rerekētanga ira. Ko te whakahiato whanaketanga o nāianei e tautuhi ana i te whanaketanga hei huringa i roto i te wā i roto i tēnei rerekētanga iranga. Ka nui ake, ka iti ake rānei te auau o tētahi ira motuhake e pā ana ki ētahi atu momo ira o taua ira. Ka ngaro te rerekētanga ina tae atu tētahi ira hou ki te wāhi whakapumau - ina ngaro atu i te iwi whānui, ka whakakapi rānei i te ira tupuna katoa. Mā te tīpakonga māori anake e puta ai te kunenga mēnā he nui te rerekētanga iranga i roto i te iwi whānui. I mua i te kitenga o te ira Mendelian, ko tētahi whakaaro noa ko te whakaranu i te kainga tupu. Engari ki te whakaranu i te kainga tupu, ka tere ngaro te rereketanga iranga, e kore ai e taea te whanaketanga ma te whiringa maori. Ko te tikanga o Hardy-Weinberg e whakarato ana i te otinga ki te āhua o te pupuri i te rerekētanga i roto i tētahi iwi whānui me te ira Mendelian. Ko ngā auau o ngā ira (te rerekētanga i roto i tētahi ira) ka noho pūmau i te kore tīpakonga, te hurihanga, te hekenga, me te nekeneke iranga. Ka puta mai te rerekētanga mai i ngā huringa i roto i te huinga ira, te whakarerekētanga o ngā ira mā te whakatipuranga ā-ira, me te hekenga i waenganui i ngā iwi whānui (te rere ira). Ahakoa te whakaurunga tonutanga o ngā rerekētanga hōu mā te irakētanga me te rere ira, he ōrite te nuinga o te huinga ira o tētahi momo ki ngā tāngata katoa o taua momo. Heoi anō, ahakoa he iti noa iho ngā rerekētanga i roto i te momoira, ka arahi ki ngā rerekētanga nui i roto i te momoira: hei tauira, he rerekē noa iho te 5% o ngā huinga ira tangata me ngā huinga ira tangata.  Pātai: He aha te kunenga i runga i te ariā o te kunenga o nāianei?
