Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Mabhiza nembongoro dzinenge dzisingabereki nokuti mabhiza ane makromosome 64 asi mbongoro dzine 62, zvichiita kuti pave nevana vane makromosome 63. Makondo akajairika zvikuru kupfuura makondo. Izvi zvinofungidzirwa kuti zvinokonzerwa nezvinhu zviviri, chokutanga chichiratidzwa mumhando dzemakate, kuti apo nhamba yemachromosome echirume inenge yakakura, mwero wokubereka unodonha. Kugadzirwa kweprogesterone kwakaderera kwejenny kunogonawo kutungamirira kukuparara kwembudzi kwokutanga. Mukuwedzera, pane zvikonzero zvisinei zvakananga nebiology yokubereka. Nemhaka yokuzvibata kwakasiyana pakuita bonde, majaya anowanzova nechido chokufukidza mares kupfuura zvinyamututa zvokurera jennies. Uyezve, mbizi dzinowanzokura kudarika jennies uye nokudaro dzine nzvimbo yakawanda yokuti mwana anozotevera akure mudumbu, zvichiguma nemhuka yakakura pakuzvarwa. Zvinowanzodavirwa kuti mbongoro dzinobatwa nyore uye dzakasimba mumuviri kudarika mbongoro, zvichiita kuti dzive dzakanaka kuti dziberekwe nevafudzi. Vana vemombe dzembongoro-mbongoro vanonzi zonkey, zebroid, zebrass, kana zedonk; mbongoro yembongoro izita rekare, asi richiri kushandiswa mune dzimwe nzvimbo nhasi. Mashoko ari pamusoro apa anowanzoreva mahybrids anoberekwa nokuita kuti mbongoro hadzi iberekane nembongoro hadzi. Zebra hinny, zebret uye zebrinny zvose zvinonongedzera kumuchinjikwa wechikadzi zebra nembongoro. Zebrinnies hadziwanikwi zvikuru kupfuura zedonkies nemhaka yokuti mhuka dzomusango hadzi dziri muutapwa dzinokosha zvikurusa padzinoshandiswa kubudisa mhuka dzomusango dzeropa rakazara. Hapana mhembwe hadzi dzakakwana dzinobereka dziri muutapwa dzisingafaniri kubatanidzwa; hapana muganhu wakadaro panhamba yemadhongi hadzi anobereka.  Mubvunzo: Mabhiza nembongoro zvakavhenganiswa zvine makromosome mangani?
