Nishan (emyaka 28) yajja mu ddwaaliro ku lunaku olwo ng’awulira situleesi nnyo era ng’anyiize. Amangu ddala nga yayingidde mu kisenge, yasiiga ensingo n’atunula wansi, n’asirika okumala ebbanga ddene.
"Doctor, nasomye ekiwandiiko ku mutimbagano ekiro ekikeesezza olwaleero ekikwata ku kitabo kya Richard Dawkins ekya 'The Selfish Gene'. Okusinziira ku kyo, ffenna tuli byuma byokka, nga robots, ebikoleddwa okuzaala obuzaale, nga tukola okusinziira ku buzaale bwaffe. Taata ne jjajja balina puleesa ne sukaali. Kale ekyo kitegeeza nti obuzaale bwange butegekeddwa okunlwaza mu ngeri y'emu? Tetulina ddembe lyonna kufuga bulamu bwaffe?" Nishan bwe yabuuzizza mu kutya okungi.
Natunuulira Nishan ne nnyenya mu ngeri ey’okusaasira. "Nishan, totya. Richard Dawkins, eyawandiika ekitabo ekyo, yakozesa ekigambo 'okwefaako' ng'olugero lw'ebisolo lwokka. Ekyo tekitegeeza nti tetulina ddembe lya kubeerawo. Wadde obuzaale bwe pulaani y'obulamu bwaffe, tetuli robots zokka. Tusobola okufuga engeri obuzaale bwaffe gye bukolamu nga tuyita mu mize gyaffe emirungi, endya, n'obulamu obulungi obw'omutwe. Mu sayansi w'obusawo, kino." kiyitibwa epigenetics. Kale leero, ka twogere ku nkolagana eriwo wakati w'endowooza eno eya ssaayansi ey'obuzaale obw'okwefaako n'obulamu bwaffe obwennyini."
Ensengekera z’obuzaale kye ki?
Ensengekera z’obutonde (genes) buba butonotono obukwata ku biramu obulimu ebiragiro eby’ekyama ebyetaagisa okuzimba n’okuddukanya omubiri gwaffe gwonna. Zisangibwa mu molekyo za DNA munda mu butoffaali bwaffe.
Obuzaale buno tebukoma ku kusalawo langi ya maaso gaffe, obuwanvu bwaffe, ne langi y’olususu, naye era n’engeri abaserikale baffe gye balwanyisa endwadde. Wadde ng’obuzaale buyinza okulabika ng’ebitundu by’eddagala ebitali biramu, ge maanyi amakulu agayimirizaawo obulamu ku Nsi.
Ddala obuzaale tebufa?
Ng’abantu, ffenna tufa olunaku lumu. Emibiri gyaffe si gya lubeerera. Naye obuzaale obuli munda mu mibiri gyaffe tebufa. Ziyisibwa okuva ku mulembe okudda ku mulala nga tuyita mu baana baffe n’abazzukulu.
Ensengekera z’obuzaale ezimu zisobola okuwangaala okumala obukadde n’obukadde bw’emyaka nga tezikyuse mu mibiri gy’ebisolo n’abantu. Eno y’ensonga lwaki Richard Dawkins yayita obuzaale “obukoppa obutafa.” Okulonda obutonde kukakasa nti obuzaale obwo bwokka obusinga okutuukagana n’obutonde era obusobola okuyisa obulungi mu mulembe oguddako bwe buwangaala.
Ebyuma ebikola ebiramu ebitambuza obuzaale (Survival Machines) .
Okusinziira ku ndowooza ya "obuzaale obw'okwefaako," emibiri gyaffe, ebisolo n'abantu, gikoleddwa okukuuma n'okuyisa obuzaale bwaffe eri omulembe oguddako. Dawkins emibiri gyaffe yagiyita "ebyuma ebiwangaala" olw'obuzaale.
- Okulya: Tulya okufuna amaanyi ge twetaaga okukuuma emibiri gyaffe n’okukuuma obuzaale bwaffe.
- Okulabirira abaana b’enkoko:Ebisolo bikola kinene nnyo okukuuma abaana baabyo, kuba bisikira ebitundu 50% ku buzaale bwabyo.
- Okwegomba mu by’okwegatta: Enkookooma ziraga amaliba gazo amalungi okusikiriza omubeezi ne ziyisa obuzaale bwazo eri omulembe oguddako.
Okuvuganya & Enkolagana mu Nkulaakulana
Okuwangaala kw’obulamu kuvuganya buli kiseera. Okuvuganya kuno kusinga kubaawo wakati w’obuzaale.
Empaka wakati w’enkima n’empologoma
Obuzaale bwa cheetah bugezaako okugiwa okudduka amangu n’enjala ensongovu. Ensigo esobole okukwata omuyiggo n’ewangaala. Ate obuzaale bw’empologoma bugezaako okugiwa okuddamu okw’amangu n’okusobola okwekweka. Bwe kityo, obuzaale bw’enjuyi zombi bugezaako okusingagana, era kino kiyitibwa empaka z’emmundu ez’enkulaakulana.
Enkolagana mu by’enkulaakulana
Wadde ng’obuzaale buba bwa bokka, oluusi okukolagana kyetaagisa nnyo okusobola okuwangaala kw’obuzaale. Ng’ekyokulabirako, enjuki bwe zifukirira ebimuli, ziyonka obubisi. Enkolagana wakati w’enjuki n’ekimuli eyamba okutwala obulungi obuzaale bw’enjuyi zombi.
Hox genes: Ebiseera by’obutonde ebiyitibwa capsules
Hox genes kibinja kya buzaale kikulu nnyo ekisalawo ensengekera y’omubiri (omutwe, omugongo, ebitundu by’omubiri) gw’ebisolo.
Obuzaale buno busigadde nga tebukyusiddwa mu ngeri eyeewuunyisa okumala obukadde n’obukadde bw’emyaka. Okufaanagana wakati w’obuzaale bwa Hox obusalawo enkula y’omubiri gw’enseenene n’obuzaale bwa Hox obusalawo enkula y’omubiri gw’omuntu kutuuse n’okwewuunyisa bannassaayansi. Bino bitundu bya kiseera bituufu eby’obutonde, era buno bukakafu bwa maanyi nti obulamu bwonna ku Nsi bwava mu jjajjaabwe ow’awamu.
Ensengekera y’obuzaale eyeefaako bokka n’enneeyisa y’omuntu
Emabega w’enneeyisa yaffe ezisinga obungi waliwo ebiragiro ebiweebwa obwongo okukakasa nti obuzaale buwangaala.
- Okwagala kw’abazadde: Abazadde beetegefu okwefiiriza kwonna ku lw’abaana baabwe kubanga obuzaale bwabwe buli mu baana. Mu buzaale, kino kiyitibwa "okulonda ab'eŋŋanda".
- Omukwano n’Obufumbo: Bwe tulonda omubeezi, mu butamanya tutera okulonda omuntu omulamu obulungi era ng’abaserikale b’omubiri abalungi, n’ekigendererwa eky’okuzaala abaana ab’amaanyi.
🚨 Okwegendereza n'okubuulirira abasawo
Bwe wabaawo embeera z’obuzaale ezitambulira mu maka go, kikulu okuzimanya.
Embeera z’osaanidde okwebuuza ku musawo amangu ddala n’ofuna amagezi:
- Singa ab’omu maka abawerako ab’oku lusegere baba bafunye kookolo, omutima oba okulemererwa kw’ekibumba ku myaka emito.
- Singa enjuyi zombi mu maka g’abafumbo abanoonya okufumbiriganwa baba n’obuzibu bw’omusaayi obusibuka nga Thalassemia.
- Bw’oba ofuna embuto eziddirira ng’osuubira omwana.

❓ Ebibuuzo ebirala by’oyinza okuba nabyo (FAQ) .
Ensengekera y’obuzaale eyeefaako bokka etegeeza nti ffenna tuzaalibwa nga twefaako bokka? ▼
Nedda.Ekigambo ‘okwefaako’ kikozesebwa wano okutegeeza omuze gw’obutonde ogw’obuzaale okuyisa kkopi zaabyo eri omulembe oguddako, so si kunnyonnyola ndowooza ya muntu oba enneeyisa y’empisa. Mu butuufu, endowooza eno ennyonnyola nti enkolagana n’okufaayo ku balala wakati w’abantu n’ebisolo bitera okuyamba obuzaale okuwangaala.
Singa omuntu mu maka gange alina obulwadde obw’obuzaale, mazima ddala nange nnaabufuna? ▼
Nedda Wadde ebyafaayo by’amaka biyinza okwongera ku bulabe bw’okufuna obulwadde, tekikakasa nti ojja kubufuna 100%. Endwadde nnyingi, gamba nga puleesa, ssukaali, n’endwadde z’omutima, ziva ku bintu bingi. Kwe kugamba, ng’oggyeeko obuzaale, ebintu eby’ebweru gamba ng’engeri gy’obeera, endya, dduyiro, ne situleesi nabyo bye bisalawo oba obuzaale obwo bukola oba nedda.
Okukebera obuzaale kusobola okuzuula endwadde nga bukyali? ▼
Yee. Okusinziira ku ssaayansi w’obusawo aliwo kati, okukebera obuzaale nga okozesa sampuli y’omusaayi kuyinza okuzuula endwadde ez’obuzaale z’oyinza okuba mu bulabe bw’okufuna mu biseera eby’omu maaso (e.g. BRCA1/BRCA2 gene mutations that determine the risk of breast cancer). Okuzuula kuno nga bukyali kikusobozesa okukola eby’obujjanjabi ebyetaagisa n’okukyusa mu bulamu bw’omuntu okusobola okwetangira obulwadde buno.
Okulongoosa obuzaale nga tukozesa tekinologiya nga CRISPR tekirina bulabe? ▼
CRISPR-Cas9 tekinologiya ow’omulembe asobola okusala obulungi n’okukyusa DNA. Mu kiseera kino kikeberebwa mu bujjanjabi okujjanjaba endwadde ez’amaanyi ez’obuzaale nga hemophilia ne sickle cell anemia, era nga kifunye obuwanguzi bungi. Wabula wakyaliwo okunoonyereza kwa ssaayansi okukakali n’enkola z’okulungamya ezigenda mu maaso okwetoloola ensi yonna ku nsonga z’obukuumi bwayo n’empisa.
