Isingeniso: Izinja zesifazane nokuzalana
Izinja ezinsikazi, njengezilwane eziningi ezincelisayo, zizalana ngokocansi. Zinesimiso sokuzala esizivumela ukuba zithwale futhi zizale inzalo. Izinja ezinsikazi zingena ekushiseni, noma i-estrus, njalo ezinyangeni eziyisithupha kuya kweziyishumi nambili, lapho zisuke zamukele ukukhwelana futhi zingakhulelwa. Isikhathi sokumitha kwezinja cishe yizinsuku ezingama-63, emva kwalokho zizala ilitha lemidlwane.
Umqondo wobaba abaningi
I-Multiple paternity igama elisetshenziswa ukuchaza isimo lapho umdlwane unobaba abangaphezu koyedwa. Lokhu kungenzeka lapho inja yensikazi ihlangana namaduna amaningi phakathi nomjikelezo wayo wokushisa, futhi isidoda sowesilisa ngamunye sivundisa iqanda lakhe elilodwa noma amaningi. Ukuba nobaba abaningi akuvamile ezinjeni, ikakhulukazi ezinjeni lapho abesifazane bangase bahehe amadoda amaningi ngesikhathi sokushisa.
Ingabe abesilisa abaningi bangamithisa inja yesifazane?
Yebo, kuyenzeka ukuthi abesilisa abaningi bakhulelise inja yesifazane. Lapho inja yensikazi ishisa, ikhipha ama-pheromone aheha izinja zesilisa. Uma amadoda angaphezu kweyodwa eshada nensikazi phakathi nomjikelezo wayo wokushisa, isidoda ngasinye sendoda singavundisa iqanda elihlukile, okuholela ekulahlekeni kobaba abaningi. Kodwa-ke, kufanele kuqashelwe ukuthi akuwona wonke ama-puppies emfucumfucu azoba nobaba abahlukene. Abanye bangase babe nobaba oyedwa, kuyilapho abanye babe nobaba abahlukene.
I-biology ngemuva kobaba abaningi
Ukuba nobaba abaningi ezinjeni kungenzeka ngoba izinja zesifazane zikhulula amaqanda amaningi phakathi nomjikelezo wazo wokushisa. Iqanda ngalinye lingavundiswa yisidoda esihlukile, okuholela emidlwaneni enobaba abahlukene. Amaqanda avundisiwe abe esekhula abe imibungu, ekhula ibe imidlwane. Imidlwane ingase ibe nezici ezingokomzimba nobuntu obuhlukene, kuye ngokwakheka kwayo kofuzo. Ukuba nobaba abaningi kungaba yinzuzo ekuhlukeni kwezakhi zofuzo, kodwa kungase kube nomthelela ekuzaleni nempilo.
Izinto ezithinta ubaba abaningi
Kunezici eziningana ezingaba nomthelela ekutheni umdlwane unabo obaba abaningi. Esinye sezici ezibaluleke kakhulu isikhathi sokukhwelana. Uma inja yensikazi ihlangana nabesilisa abaningi besondelana ngesikhathi, maningi amathuba okuthi isidoda ngasinye wesilisa sivundise iqanda elihlukile. Ezinye izici ezingaba nomthelela wokuba ubaba abaningi zihlanganisa inani labesilisa abahlangana nensikazi, iminyaka nempilo yensikazi, kanye nofuzo lwezinja zesilisa.
Unganquma kanjani ukuthi udoti unobaba abaningi
Ukunquma ukuthi udoti lwemidlwane lunobaba abaningi kungaba inselele, kodwa kungenzeka. Enye indlela yokwenza lokhu ngokuhlolwa kwe-DNA. Ukuhlolwa kwe-DNA kungakhomba amaphrofayili ofuzo omdlwane ngamunye futhi kunqume ukuthi unobaba abafanayo noma abahlukene. Enye indlela yokunquma ububaba abaningi ngokusebenzisa izici zomzimba. Imidlwane enobaba abahlukene ingase ibe nemibala yejazi ehlukene, izimpawu, nezici zomzimba.
Imithelela yobaba abaningi ekuzaleni
Ukuba nobaba abaningi kungaba nomthelela ekuzaleni. Abafuyi abafuna ukugcina imigqa ehlanzekile bangase bafune ukugwema ubaba abaningi, njengoba kungethula ukuhlukahluka kofuzo okungafunwa. Ukuzalela obaba abaningi nakho kungaba inselele, njengoba kudinga isikhathi esicophelelayo kanye nokuphathwa kokukhwelana. Kodwa-ke, ukuzala abantu abaningi kungaba yinzuzo ekuhlukeni kwezakhi zofuzo futhi kungaholela emidlwaneni enempilo enohlu olukhulu lwezimpawu zomzimba nezokuziphatha.
Umthelela wobaba abaningi empilweni yezinja
Ukuba nobaba abaningi akunawo umthelela oqondile empilweni yezinja. Kodwa-ke, kungethula ukuhlukahluka kofuzo okungase kube yinzuzo noma kube yingozi empilweni yenzalo. Ukuhlukahluka kwezakhi zofuzo kungasiza ekunciphiseni amathuba okuba nezifo ezizuzwe njengefa futhi kwandise ukumelana nezingcindezi zemvelo. Kodwa-ke, kungandisa futhi amathuba okuba nokuphazamiseka kofuzo.
Ukucatshangelwa kokuziphatha kobaba abaningi
Ubaba abaningi kuphakamisa ukucatshangelwa kokuziphatha ekuzaleni izinja. Abafuyi kufanele bacabangele inhlalakahle yezinja kanye nomthelela ongaba khona wozalo abaningi empilweni nasenhlalakahleni yemidlwane. Abanye abafuyi bangase balingeke ukuba bazalele obaba abaningi ukuze bazuze ngokwezimali noma bakhe izinhlobo ezintsha, ezingase zingabi nasimilo. Kubalulekile ukuqinisekisa ukuthi izinqubo zokuzalanisa zilungile futhi zinomthwalo wemfanelo.
Izinkinga zomthetho eziphathelene nobaba abaningi ekuzaleni izinja
Ayikho imithetho ethile noma iziqondiso eziphathelene nobaba abaningi ekuzaleni izinja. Kodwa-ke, abafuyi kufanele balandele izinqubo zokuzalanisa ezilungile futhi ezinomthwalo wemfanelo futhi baqinisekise ukuthi bathobela noma yimiphi imithetho efanele yenhlalakahle yezilwane. Abazalanisi kufanele futhi baphumele obala mayelana nemikhuba yokuzalanisa abayisebenzisayo kanye namandla okuba nobaba abaningi.
Ungavimba kanjani ubaba abaningi ekuzaleni izinja
Ukuze uvimbele ukuzala abantu abaningi, abafuyi bangasebenzisa izindlela zokuzalanisa ezilawulwayo, ezifana nokuzalanisa okwenziwa. Ukuzalanisa okuzenzela kuvumela abafuyi ukuthi balawule isikhathi kanye nenani lokukhwelana, kunciphisa amathuba okuba nobaba abaningi. Abafuyi bangakwazi futhi ukusebenzisa ukuhlolwa kwe-DNA ukuze banqume ukuthi imidlwane ingobani futhi baqinisekise ukuthi izalela izici ezithile noma izici ezithile.
Isiphetho: Ukuqonda ubaba abaningi ezinjeni zesifazane
Ukuba nobaba abaningi ezinjeni zezinsikazi kungenzeka futhi kungaba nemiphumela ezuzisayo neyingozi. Abafuyi kufanele baqaphele amathuba okuba nobaba abaningi futhi bathathe izinyathelo zokuqinisekisa izinqubo zokuzalanisa ezilungile nezinesibopho. Ukuqonda isayensi yezinto eziphilayo kanye nemithelela yokuba nobaba abaningi kungasiza abalimi ukuba benze izinqumo ezinolwazi mayelana nezinqubo zokuzalanisa futhi baqinisekise impilo kanye nokuphila kahle kwemidlwane.
