M'mawu osavuta, chiganizocho "chibadwa" chikutanthawuza chirichonse chimene chimakhudzana ndi mchitidwe wa jini wa munthu omwe uli mkati mwa selo iliyonse yamoyo. Zachibadwa ndizomwe zimapangitsa kuti munthu akhale ndi moyo wambiri komanso zamoyo zina.
Chibadwa
Zamoyo zimapangidwa ndi DNA, kapena kuti deoxyribonucleic acid. Malingana ndi Human Genome Project - ntchito yofufuzira m'mayiko osiyanasiyana omwe amachititsa kuti azindikire ndi kupanga mapangidwe a chibadwa cha anthu - tili ndi majini 20,000 - 25,000.
Chodabwitsa, pafupifupi majini 99 mwa majini ndi ofanana ndi anthu onse, ndi gawo laling'ono lomwe liripo chifukwa cha kusiyana komwe timawona mu msinkhu, mtundu wa khungu, kulemera, ndi zina.
The Genetic Theory of Aging
Chikhulupiriro cha ukalamba chimasonyeza kuti moyo wautali umadaliranso ndi majeremusi athu, ndipo kafukufuku wina - monga maphunziro okhudza mapasa ofanana - amachirikiza mfundoyi. Kafukufuku wina adayerekezera kuti moyo wa munthu uli ndi 25 peresenti yokha chifukwa cha chibadwidwe chawo ndipo nthawi zambiri zimakhudzidwa ndi zochitika za moyo monga zakudya ndi masewera olimbitsa thupi, ndi zizolowezi zoipa monga kusuta kapena kumwa mowa mopitirira muyeso.
Komanso, kafukufuku wa sayansi ya zaumoyo akufuna kudziwa chifukwa chake majini amatha "kusinthika" m'thupi, ndipo ena sali, omwe amachititsa thupi kapena chiopsezo ku matenda, mwachitsanzo. Omwe amatchedwa epigenetics, malo ophunzirirawa akuyang'ana zinthu zomwe zimakhudza amayi monga kusamalidwa kwa amayi kapena kusungidwa kwa chilengedwe, ndipo amatha kufotokozera chifukwa chake mapasa omwe ali ofanana ali ndi zofanana.
Genetic vs. Kudzetsa
Ngakhale kuti mawu oti majini amagwiritsidwa ntchito mosasinthasintha ndi chiganizo choloĊµa cholowa, mawu awa sikutanthauza chinthu chomwecho. Mwachitsanzo, khansara ndi matenda a chibadwa chifukwa imakhala ndi jini mkati mwa selo (zomwe zimachititsa kuti selo ligawike mosalekeza), koma khansa yokha ingayambidwe ndi dzuwa kapena fodya ndipo sikuti imachokera kwa makolo anu.
