Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Mwana ari mudumbu ndiye anenge achangotanga kukura. Kazhinji, muzvinhu zvinorarama zvinobereka zvepabonde, mwana ari mudumbu anovapo kubva muzygote, sero rimwe chete rinobva pakuita kuti zai rechikadzi ribatane nesperm cell rechirume. Zygote rine hafu yeDNA kubva kumubereki mumwe nomumwe. Muzvirimwa, mhuka, uye mamwe mapurotist, zygote ichatanga kupatsanuka kupfurikidza nemitosis kuti ibudise chisikwa chine masero akawanda. Izvi zvinoguma zvaita kuti pave nemwana ari mudumbu.  Mubvunzo: Nzira yokuparadzaniswa kunoitwa zygotes inonzi chii?
