Down syndrome ndimasinthidwe amtundu omwe amapezeka mwa anthu pazifukwa zosiyanasiyana ndipo amakhala obadwa nawo pafupipafupi. Matenda ambiri omwe amakhudza anthu sianthu amtundu wa anthu okha, makamaka, nthawi zambiri ndizotheka kukumana ndi nyama zomwe zili ndi zovuta zomwe zimakhudzanso anthu. Matenda ena omwe amakhudzana ndi ukalamba kapena kuchepa kwa chitetezo cha mthupi mwa anthu ali ndi zifukwa zomwezo komanso mayanjano anyama.
Izi zikubweretsani ku funso lotsatirali, kodi pali nyama zomwe zili ndi Down syndrome? Ngati mukufuna kudziwa ngati nyama zimatha kukhala ndi Down syndrome kapena ayi, pitirizani kuwerenga nkhani iyi ya PeritoAnimal kuti mumve kukayikira uku.
Kodi Down Syndrome ndi chiyani?
Pofuna kumvetsetsa bwino nkhaniyi, choyamba ndikofunikira kudziwa kuti matendawa ndi chiyani komanso kuti ndi njira ziti zomwe zimawonekera mwa anthu.
Zambiri zamtundu waumunthu zili mu ma chromosomes, ma chromosomes ndi nyumba zopangidwa ndi DNA ndi mapuloteni omwe ali ndi gulu lokwanira kwambiri, lomwe limakhala ndi chibadwa chake motero limazindikira kwakukulu kwa chamoyocho ndipo nthawi zambiri zovuta zomwe mphatso.
Munthu ali ndi ma 23 ma chromosomes ndi Down Syndrome ndimatenda omwe amayambitsa chibadwa, popeza anthu omwe akhudzidwa ndi matendawa khalani ndi mtundu wina wa chromosome 21, omwe mmalo mokhala awiri, ndi atatu. Izi zomwe zimapangitsa Down Syndrome ndizodziwika ndi zamankhwala monga trisomy 21.
Ndi kusintha kwa majini ali ndi udindo mikhalidwe yomwe timawona mwa anthu omwe akhudzidwa ndi Down syndrome komanso omwe amatsagana ndi a kuwonongeka kwina kwa kuzindikira komanso kusintha kwa kukula ndi minofu ya minofu, kuwonjezera apo, Down's Syndrome imalumikizidwanso ndi chiopsezo chachikulu chovutika ndi matenda ena.
Nyama zomwe zili ndi Down Syndrome: kodi ndizotheka?
Pankhani ya Down syndrome, ndi mwapadera matenda amunthu, popeza gulu la chromosomal la anthu ndi losiyana ndi la nyama.
Komabe, zikuwonekeratu kuti nyama zimakhalanso ndi chidziwitso cha chibadwa chofananira, makamaka, ma gorilla ali ndi DNA yomwe ikufanana ndi DNA ya anthu peresenti ya 97-98%.
Popeza nyama zimayanjananso motsatira ma chromosomes (awiriawiri a ma chromosome amadalira mtundu uliwonse), amatha kudwala ma chromosome ena ndipo amasintha kukhala ozindikira komanso amthupi, komanso kusintha kwa maatomiki komwe kumawapangitsa kukhala ndi mawonekedwe aboma.
Izi zimachitika, mwachitsanzo, mu makoswe labu omwe ali ndi trisomy pa chromosome 16. Kuti timalize funso ili, tiyenera kutsatira mawu awa: nyama zimatha kusinthidwa ndi majini pa chromosome ina, koma Sizingatheke kukhala ndi nyama zomwe zili ndi Down syndrome, popeza ndi matenda okhaokha omwe amayamba chifukwa cha trisomy pa chromosome 21.
Ngati mukufuna kupitiliza kuphunzira zambiri za nyama, onaninso nkhani yathu yomwe imayankha funso: Kodi nyama zimaseka?
