I-Down syndrome ingukushintshwa kwezakhi zofuzo okwenzeka kubantu ngezizathu ezahlukahlukene futhi kuyisimo sokuzalwa njalo. Izifo eziningi ezithinta abantu azigcini ezinhlotsheni zabantu, empeleni, ezikhathini eziningi kungenzeka ukuthi uhlangane nezilwane ezinezifo ezithinta abantu. Ezinye izifo ezihambisana nenqubo yokuguga noma ukwehla kwamandla omzimba kubantu zinezimbangela nezinhlangano ezifanayo ezilwaneni.
Lokhu kukuletha kulo mbuzo olandelayo, zikhona yini izilwane ezine-Down syndrome? Uma ufuna ukwazi ukuthi ngabe izilwane zingaba ne-Down syndrome noma cha, qhubeka ufunda le ndatshana yePeritoAnimal ukucacisa lokhu kungabaza.
Yini i-Down Syndrome?
Ukuze ucacise lolu daba ngokwanele, okokuqala kubalulekile ukuthi wazi ukuthi yini le sifo nokuthi yiziphi izindlela ezibangela ukuthi ivele kubantu.
Imininingwane yofuzo yabantu iqukethe ama-chromosomes, ama-chromosomes ayizakhiwo ezakhiwe yi-DNA namaprotheni anezinga eliphakeme kakhulu lenhlangano, aqukethe ukulandelana kofuzo ngakho-ke anquma ngezinga elikhulu ubunjalo bomzimba futhi ezikhathini eziningi izifo izipho.
Umuntu unamabhangqa angama-23 ama-chromosomes ne-Down Syndrome yisifo esinesifo sofuzo, ngoba abantu abathintekile yilesi sifo unekhophi eyengeziwe ye-chromosome 21, okuthi esikhundleni sokuba ngababili, bathathu. Lesi simo esiveza iDown Syndrome saziwa ngokwezokwelapha njenge-trisomy 21.
Ikona ukuguqulwa kofuzo unesibopho sezici zomzimba esizibonayo kubantu abathintekayo yi-Down syndrome futhi abahambisana no-a ukukhubazeka okuthile kwengqondo kanye nezinguquko ekukhuleni nasezicutshini zemisipha, ngaphezu kwalokho, iDown's Syndrome nayo ihlotshaniswa nengozi ephezulu yokuhlushwa ezinye izifo.
Izilwane ezine-Down Syndrome: kungenzeka?
Endabeni ye-Down syndrome, iyi- isifo esihlukile somuntu, ngoba inhlangano ye-chromosomal yabantu ihlukile kuneyezilwane.
Kodwa-ke, kusobala ukuthi izilwane nazo zinolwazi oluthile lofuzo olunokulandelana okuthile, empeleni, ama-gorilla ane-DNA elingana ne-DNA yomuntu ngamaphesenti angama-97-98%.
Njengoba izilwane zinokulandelana kwezakhi zofuzo nazo ezi-ode kuma-chromosomes (ama-chromosomes ngazimbili ancike ohlotsheni ngalunye), angaba nezinkinga ezithile ze-chromosome ethile futhi lokhu kuguqulele ebunzimeni bokuqonda nobungokomzimba, kanye nezinguquko ze-anatomical ezibanikeza isimo sesimo.
Lokhu kwenzeka, ngokwesibonelo, kufayela le- amagundane elebhu one-trisomy ku-chromosome 16. Ukuphetha lo mbuzo, kufanele sinamathele kulesi sitatimende esilandelayo: izilwane zingabhekana nokushintshwa kwezakhi zofuzo nobunzima kwi-chromosome ethile, kepha Akunakwenzeka ukuba nezilwane ezine-Down syndrome, njengoba kuyisifo somuntu kuphela futhi esibangelwa i-trisomy ku-chromosome 21.
Uma unesifiso sokuqhubeka nokufunda kabanzi ngomhlaba wezilwane, bheka futhi nendatshana yethu ephendula lo mbuzo: Ingabe izilwane ziyahleka?
