I-Zygotic ibhekisela kwi-zygote, iqanda elizaliswe yi-sperm eliza kukhula libe ngumbungu kwaye likhule libe ngumntwana. Amawele e-Monozygotic avela kwiqanda elilodwa kunye nesidoda esahlukana kabini emva kokukhulelwa.

Ngenxa yokuba amadoda athatha ii-chromosomes ze-X (zebhinqa) kunye ne-Y (zesilisa), anokukwazi ukubamba umxhesho wokuxhaswa kwegazi kwaye azidlulise kunye neentombi zawo, ukwandisa amathuba abo intombi yokuba namawele omzalwana.

Nangona kunjalo, ukuba ne-gene ye-hyperovulation ayinyuli amathuba omntu wokuzala amawele angamaqabane. Indoda ithwala imfuza, kodwa ayitshintshi iphethini ye-ovulation yomama wabantwana bayo. Unayo iizakhi zakhe ezilawula i-ovulation. Endaweni yoko, yayiya kuba yintombi yakhe eyayifumana iifa lakhe. Kungenxa yoko amawele ngamanye amaxesha acinga ukuba "anqumle isizukulwana."
