<prompt> Fingqa isihloko: Ngokokuqala ngqá kwezakhi zofuzo, ososayensi baye bahlela ngokulandelana iqoqo elikhulu kunawo wonke lamagciwane abantu abake bathola kulo. Lo msebenzi omkhulu wawuhlanganisa ukulandelana kwe-DNA yabantu base-Iceland abangu-2.636 nokuqhathaniswa kwabo nokulandelana okuyingxenye kwabanye abangu-104.000. Phakathi kokutholakala okuyinhloko, iqoqo lemininingwane lisikisela ukuthi uyise wesintu - ukhokho wethu wesilisa osanda kutholakala - waphila eminyakeni ephakathi kuka - 174 000 no - 321 000 edlule. Skrolela phansi ukuze ubone ividiyo. Ngokokuqala ngqá kwezakhi zofuzo, ososayensi baye bahlela ngokulandelana iqoqo elikhulu kunawo wonke lamagciwane abantu abake baba nawo esikhungweni esisodwa sabantu. Lo msebenzi omkhulu wawuhlanganisa ukulandelana kwe-DNA yabantu base-Iceland abangu-2 636 nokuqhathaniswa kwabo nokulandelana okuyingxenye kwabanye abangu-104 000 okwembula ukuqonda kokuziphendukela kwemvelo komuntu. Ososayensi babheka i-Iceland njengomgodi wegolide wokucwaninga ngezakhi zofuzo. Leli zwe lasungulwa iqembu elincane lezakhamuzi ezivela eYurophu ezafika eminyakeni engaba ngu - 1 100 edlule futhi lahlala lihlukanisiwe iminyaka eyinkulungwane eyalandela. Ngenxa yokuthi inani labantu e-Iceland linokuhlukahluka okuncane kakhulu kwezakhi zofuzo, ososayensi bangakwazi ukuthola kalula izinhlobo zofuzo ezandisa amathuba okuba umuntu agule. I-Iceland nayo inerekhodi eliqinile lozalo, ngenxa yemibhalo yomlando elondolozwe kahle. Lolu hlu lwezinsuku, olusekelwe ekubalweni kwamazinga okuguquka kwesimo sabantu, luphikisana nokutholakele kwangaphambilini okuthi uyise wabo bonke abantu waphila eminyakeni engaba ngu-340 000 edlule. Ososayensi manje balinganisela iminyaka yakhe yokuba iminyaka engu - 239 000 ubudala - usuku oluseduze nokhokho wesintu wesifazane ovame kakhulu okukholelwa ukuthi waphila eminyakeni engu - 200 000 edlule. Ngaphandle kokuqonda ukuziphendukela kwemvelo, ososayensi bathi iqoqo lemininingwane lizobasiza bathole izakhi zofuzo eziguqukile ezivikela ngokwemvelo iqembu labantu elingavamile ezifweni ezithile. Kuze kube manje, lo msebenzi uye wanikeza imiphumela ethembisayo esiza ekuboneni izinhlobo zezakhi zofuzo eziyizigidi ezingu-20 phakathi kwabantu base-Iceland. Phakathi kwalezi zinhlobonhlobo, ososayensi baseReykjavik-based DeCode Genetics kakade sebethole izakhi zofuzo ezandisa ingozi yesifo sika-Alzheimer, izinkinga zesibindi nezengqamuzana yegilo. Lo msebenzi uyisibonakaliso samandla ayingqayizivele esiwanikezwa ukulandelana,  <response>: Ososayensi bahlela ngokulandelana ama-genome amakhulu kunawo wonke ake atholakala esizweni esisodwa. Le datha yembula ukuguquka kwezakhi zofuzo okumangazayo kubantu base-Iceland. UData waveza nokuthi ubaba wesintu mdala kunalokho obekucatshangwa ekuqaleni. Amaphesenti angu-8 abantu anegene elingasebenzi nhlobo. Ucwaningo luthole izakhi zofuzo ezandisa ingozi yesifo i-Alzheimer nesifo sesibindi. Ososayensi bathi le mininingwane izobasiza ukuba bathuthukise izindlela zokwelapha izifo ezingcono.
