Muchirevo chakareruka, chirevo che "genetic" chinoreva chinhu chipi nechipi chine chokuita nehutano hwemunhu hunenge huri mukati memasero ose ehupenyu. Genesisi ndiyo inonyanya kukosha yehupenyu hwevanhu uye zvimwe zvipenyu.
Genesisi
Zvitsva zvinoumbwa neDNA, kana kuti deoxyribonucleic acid. Maererano neHuman Genome Project - inyika dzakawanda dzinotsvakurudza dzakaitwa kuti dzive nekuona mapepa ekuenzanisa kwevanhu - isu tinofungidzirwa 20 000 - 25 000 magenhi.
Zvinotoshamisa kuti inenge 99% yejenisi yakafanana kune vanhu vose, nechinosara chechikamu chinokonzera kusiyana kwatinoona mukukwirira, ruvara rweganda, uremu, nezvimwe zviito zvemuviri.
The Genetic Theory of Aging
Nhoroondo yehutano yekukwegura inoratidza kuti upenyu hurefu hunotarirwawo nemararamiro edu, uye kumwe kutsvakurudza - zvakadai seongororo dzinosanganisira mapatya akafanana-anotsigira iyi hypothesis. Zvimwe zvidzidzo zvakafungidzira kuti hupenyu hwomunhu hunenge 25% chete hunokonzerwa nehupenyu hwavo uye huzhinji hunoita kuti huve nemafungiro emararamiro akaita sekudya uye kuita zvekuita, uye tsika dzinokuvadza sekusvuta kana kushandisa doro zvisina kunaka.
Uyezve, imwe nzvimbo inotanga kuongorora svesa yehutano inofanirwa kuziva kuti nei mamwe majini "akashandurwa" mumuviri, uye vamwe haasi, zvichiita kuti zvimwe zvisikwa zvemuviri kana kutambura zvirwere, somuenzaniso. Inonzi epigenetics, nzvimbo iyi yekudzidza inotarisa zvinokonzera zvinhu zvakadai sekushungurudzika kwevana kana kusununguka kwezvakatipoteredza, uye zvinogona kutsanangura zvishoma kuti nei zvakafanana mapatya ane maitiro akasiyana kunyange zvazvo ane chimiro chakafanana.
Genetic vs. Hereditary
Kunyange zvazvo izwi rokuti genetic rinowanzoshandiswa zvakasiyana-siyana neshoko rechirevo rinotora nhaka, mazwi aya haarevi kureva chinhu chakafanana. Semuenzaniso, kenza chirwere chetachiona mukuti inosanganisira mazamu ari mukati memusero (zvichiita kuti sero riparadzanise risingaregi), asi kenza pachayo inogona kukonzerwa nezuva kana kuti fodya iripo uye haisi iyo inotora nhaka kubva kuvabereki vako.
