Izinja yizilwane eziyingxenye yezinhlobo ezinezakhi zofuzo ezahlukahlukene kakhulu emhlabeni futhi yingakho lapho sazi uhlu olukhulu kakhulu lwamakilasi kanye nokuncipha kwezinhlobo zezinja, iningi labanikazi baqala ukuzizwa bekhungathekile njengoba bengakwazi ukunquma indlela ethile isiphi isilwane noma uhlobo luni isilwane sakho esivela kuso.
Kungakho namuhla sinethuba lokuthola ngenxa yokuhlolwa kwe I-DNA yezinja.
Ifa lofuzo ezinjeni
Kusenabanikazi abenza umzamo wokuqagela ukuthi inja ingowaluphi uhlobo ngokucabangela ukubukeka kwayo nokuziphatha kwayo, kepha ufuzo ezinjeni uphethe i-morphology, kanye nengxenye encane yokuziphatha kwabo, ngenxa yalesi sizathu, ifa lofuzo ezinjeni ligeleza ngqo ngemibala, usayizi noma isimilo.
Unolwazi lwe imvelaphi ephethe inja ukuba yi-mongrel kungaba nzima impela, ikakhulukazi uma kuyinja evela endaweni yokuhlala izilwane.
Isihlahla somndeni sezinja
Kungenzeka ukubeka cishe zonke izinhlobo zezinja eqenjini elisebenzayo, noma ngabe uhlu esilukhulume ngenhla alupheli futhi lungahluka ngokubheka umfelandawonye we-canine, ngokujwayelekile, izinja zingawela ezigabeni ezinhlanu ezinkuluizinja ezizingelayo, izinja ezihambisana nazo, izinja ezisezingeni lomqaphi, izinja ezelusayo nezinja ezisebenzayo.
Ukuhlolwa kwezinja zofuzo
Kulezi zinsuku kungenzeka ukwazi okuningi ngemvelaphi yenja yethu ngokwenza ukuhlolwa kwe-DNA okulula.
Ngalokho, okudingekayo yisampula elincane lamathe akho, ngoba iyona ezosinika imininingwane edingekayo mayelana nefa le-DNA. Uma sifuna ukwenza lolu vivinyo ukwazi uhlobo lwenja yethu, njengabanikazi kufanele sigcobe ingaphakathi lomlomo wesilwane ngosizo lwamahlumela kakotini.
Lesi isivivinyo esingathatha isikhathi esingaphansi komzuzu futhi ayibangeli buhlungu.
Lapho amasampula etholakala elabhorethri, ongoti baphethe ukwenza ukuqhathanisa i-DNA yenja naleyo yezinye izinhlobo zezinja ukwenza ukuhlolwa kokuqondana. Ngokuvamile, ama-laboratories akwazi ukufinyelela ku-database ebanzi equkethe i- Amaphrofayli e-DNA ezinhlobo eziningi zezinja.
Imiphumela etholwe kulolu vivinyo isuselwa ku- hlukanisa izinhlanga ezitholakele, ngesimo somlando, ukubukeka kanye nokuziphatha.
Lezo zinhlobo zezinja ezakha amaphesenti amaningi we-DNA yenja yethu yilezo ezibonisa izinhlobo eziyinhloko noma lezo ezisezingeni eliphakathi nendawo. Uma kunjalo, inja ivame ukukhombisa izici zomzimba kanye nokuziphatha okuvame ukuba nohlobo.
Lezo zinhlanga ezimele ingxenye encane yephesenti le-DNA, yilezo ezikhombisa izinhlanga zesibili noma ezibizwa nangokuthi izinhlanga zezinga ¾, Ngakho-ke, leyo mijaho enamaphesenti aphansi kakhulu ihlukaniswa njengemijaho ephakeme noma njengemijaho esezingeni lesi-5.
Kubaluleke kakhulu ukuveza ukuthi konke lokhu kuhlukaniswa esikubalulile ngenhla akufakiwe kuzinga kunoma yikuphi ukuhlolwa izinhlobo zezinja ezivame ukutholakala emakethe futhi lokho kube nethuba lokuhluka ngokubheka ilabhorethri lapho kwenziwa khona ukuhlaziywa.
