Kulesi sihloko sizokutshela ukuthi ngabe intombazane ingakwazi yini ukukhulelwa kuye, noma ingenakwenzeka, ngokusekelwe ezimfanelweni zomzimba zomuntu.
Umuntu angakwazi yini ukukhulelwa kuye?
Sonke siyazi ukuthi ukuze umklamo uphumelele , iqanda kufanele likhule umuthi, ngakho-ke ngokobulili obungavimbelwe phakathi kwendoda nowesifazane, amathuba okukhulelwa aphezulu kakhulu. Okwamanje, ezimweni ezingavamile, okwamanje ezilotshwe kwezinye izinhlobo zezinambuzane, izinyoni nezinambuzane, ukwakheka kombungu kungabangela ukuhlukaniswa kwe-ovum engapheli.
Lesi simo sibizwa ngokuthi i-parthenogenesis futhi singaba nezinhlobo ezimbili - i-halogen ne-diploid. Esikhathini sokuqala, kusukela eqanda le-haloid ehlukanisweni, abantu bobulili besilisa noma besifazane, kanye kokubili ngesikhathi esisodwa, kwenziwa. Ngokuya ngesethi yama-chromosomes akhona emaqanda, ukwakheka kanye nobulili babantu abasha bangase bahluke, futhi kunzima ukubikezela kusengaphambili.
Nge-diploid parthenogenesis, isimo esithile esihlukile siyabonakala: amangqamuzana athile abesifazane abhekene negama lama-oocyte abambe iqhaza ekusungulweni kweqanda le-diploid, lapho ngemva kwalokho ama-embryo akhula ngokuzimela, ngaphandle kokubandakanyeka kwesilisa. Kulesi simo, abesifazane abasha kuphela abavela ekukhanyeni, okusiza ukulondoloza usayizi wesintu futhi ungavumeli ukuba bafe ezinhlotsheni zabo.
I-Parthenogenesis emvelweni ivele kuphela kulabo bantu abafa ngezinamba eziningi, okusho ukuthi bangabhekana nokuqedwa. Lezi zinhlobo zezintuthwane, izinyosi, izilonda, izinyoni nokunye. Amantombazane afanayo abhekana nakho, kungakhathaliseki ukuthi kungenzeka yini ukuba akhulelwe wona, angakwazi ukuzolile - amacala we-parthenogenesis endodeni akakaze ahlangane.
Ngakho-ke, impendulo yombuzo wokuthi owesifazane angazikhulela yini kusobala - akunakwenzeka kunoma yiziphi izimo. Ngaphezu kwalokho, amantombazane anesifo socansi, uma engafuni ukuba omama, angasebenzisa izindlela eziningi zokwelapha zanamuhla. Yiba nokuthula futhi ungazishiyi injabulo yemvelo.
