Ngabe uyazi ngempela ukuthi yini umehluko phakathi kwe-zygote nombungu? Uma uphendule ngo cha, ungakhathazeki ngoba kuvame kakhulu. Kumuthi wokuzala, amagama amaningi angaziwa ngokuphelele kubantu abajwayelekile. Ngokuvamile, uze ucwiliswe ekukhulelweni awukhathazeki ngokuhlukanisa lezo zinhlobo zamagama.
Kodwa-ke, ukwazi umehluko kungakusiza uphile ukukhulelwa kwakho ngokujulile. Uzokwazi ukwazi ngaso sonke isikhathi ukuthi yini ukukhula kwengane yakho nokuthi ikhula kanjani esibelethweni sakho. Indlela ekhetheke kakhulu yokuthola ukukhulelwa, futhi ngaphezu kwakho konke, usizo olukhulu uma kuziwa qondisisa amagama ashiwo odokotela kuwe kokuningi izibuyekezo zakho.
Ngesikhathi sokukhulelwa amasonto angama-40, ingane yakho yesikhathi esizayo izodlula ezigabeni ezintathuKuzoba i-zygote kuqala, bese iya esigabeni sombungu futhi ekugcineni kuzoba umbungu ize izalwe. Ngabe ufuna ukwazi ukuthi yini umehluko okhona phakathi i-zygote, umbungu nombungu? Sizokutshela ke.
Yini i-zygote?
I-zygote yakhiwe nge-gamete yesilisa ne-gamete yesifazane. Ingabe mayelana iseli elilodwa eliqukethe i-nucleus nama-chromosomes angama-46. Lokhu nakho kuqukethe imininingwane yezofuzo evela kubo bobabili abazali, inani lama-chromosomes angama-23 avela kubaba nama-chromosomes angama-23 avela kumama.
Isikhathi se-zygote sifushane kakhulu, ngoba sithatha cishe amahora angama-24, kepha lesi simo asiphazamisi ukubaluleka kwaso. I-zygote yisigaba sokuqala sempilo, umzuzu obaluleke kakhulu wokuzala njengoba ngaphandle kwale mpilo entsha yeseli ibingenakuba khona.
Uyini umbungu?
Ngemuva kwalawo mahora angama-24 okuqala akhona, isikhathi sombungu siyaqala, esihlala cishe amasonto ayisishiyagalombili kubantu. Umbungu kuvela ekuhlukanisweni kwe-zygote kumaseli ahlukene, ngokuya ngokukhethekile, okuzohlinzeka isidalwa esisha esinezimpawu zomzimba zezinhlobo zaso.
Ngesikhathi sombungu amaseli azohlukaniswa ngezindlela ezahlukahlukene futhi umbungu uthola amagama ahlukene ngenxa yalesi sizathu:
- UMorula. Cishe ngosuku lwesine lwesikhathi sombungu, umbungu yakhiwa iqembu elikhulu lamaseli afanayo. Amaseli kulesi sigaba aqoqene ndawonye enza uhlobo lwamajikijolo, yingakho igama elithi morula.
- I-Blastocyst. Phakathi kosuku lwesi-5 nolwesithupha lwesikhathi sombungu, amaseli aqala ngokukhethekile futhi ahlukaniswe ngamaqembu amabili. Lawa maseli azoba nesibopho sokwakha i-placenta nazo zonke izicubu ezidingekayo ukuze ukukhulelwa kwenzeke.
Umehluko phakathi kwe-zygote nombungu
Ngakho-ke, umehluko omkhulu phakathi kwe-zygote nombungu yinombolo yamaseli lokho kuzakha esimweni ngasinye. Zibaluleke ngokufana enye nenye, ngoba ngaphandle kokuba khona kwe-zygote bekungeke kwenzeke ukudala izitho ezinikeza umuntu omusha ophilayo.
Njengoba sesishilo, i-zygote yisigaba sokuqala sempilo, iseli lokuqala elivela ekuhlanganeni kwamageyimu wabazali bobabili. Kepha uma leli seli lingathuthuki futhi lingahlukani libe ngamaseli, ukukhulelwa ngeke kusebenze futhi ingane ngeke ibe khona. Ukwahlukaniswa kwamangqamuzana yilokho okuvumela i-placenta ukuthi yakheke, izicubu ezizovikela umbungu kukho konke ukukhulelwa kanye nezinto ezizokwenza ukuthi isidalwa esisha sikhule futhi sikhule sikwazi ukuhlala ngaphandle kwesizalo sikamama.
Amagama ezokwelapha kwesinye isikhathi kunzima ukuwaqonda, kepha, kuyajabulisa ukwazi ukuthi ukubonakaliswa okuncane kwezinto eziphilayo ezimbili, kungadalwa impilo entsha. Lesi isingeniso esifushane, kodwa zizwe ukhululekile ukubuza udokotela wakho ngalokhu kanye nanoma yimiphi imibuzo engavela. Ukwazi ukukhula kwengane yakho yesikhathi esizayo ngaso sonke isikhathi kuzokusiza ukubona ngeso lengqondo nokuzwa ukukhulelwa kwakho konke ngendlela ekhethekile.
