Umsila yinxalenye ebaluleke kakhulu yomzimba wesilwanyana, kuba ngawo banokubonisa indlela abavakalelwa ngayo kwaye ziyintoni iinjongo zabo. Ngesi sizathu, xa sizibuza ukuba ngaba ikhona Iikati ezingenamisila Ngokubanzi (kukho okwahlukileyo) asizukufumana mpendulo ngokwendalo yezi zinoboya, kuba ukusukela kwimvelaphi yabo bahlala bezisebenzisa kwaye ngokuqinisekileyo baya kuqhubeka benazo.
Ngenxa yakho konke ukuzala ngokuzikhethela, uguquko lwenzekile kwiikati ezibangele ukuba ezinye zizalwe zingenamsila okanye zinomfutshane kakhulu. Kodwa, ngoba?
Ziziphi iimpawu umsila iikati?
Umsila weekati Ihlala yenziwe phakathi kwe-18 kunye ne-28 vertebrae, kunye nobude obumalunga neesentimitha ezingama-25 nangona inokufikelela kwi-30cm. Njengoko besitshilo, yinxalenye ebaluleke kakhulu kunxibelelwano lwe-feline, kuba kuxhomekeke kwisikhundla sayo kunye nokuhamba kwayo iya kubonisa into enye okanye enye. Umzekelo:
- Umsila uthe nkqo, incam yearched: uziva ulungile, unobungane.
- Umsila umile, iinwele ezinoboya: ixesha, ukucaphuka.
- Umsila othe tyaba, incam ye-arched: unomdla kwinto ethile.
- Umsila ulele phantsi, kunye nencam ephezulu: yinto enqabileyo.
- Umsila phantsi okanye phakathi kwemilenze, ngeenwele ezimhlophe: uyoyika.
- Umsila phantsi, kufutshane nomzimba: ukhathazekile.
- Umsila kwelinye icala, kunye ne-arched tip: iyathandana.
Ngale nto engqondweni, kutheni kukho iikati ngaphandle kwemisila?
Amakati angenawo umsila, umbuzo wemfuza
Kunjalo. Umntu onoxanduva lokuba ikati izalwe ngaphandle kwayo iluhlobo, ngakumbi. Inee-alleles ezi-4, oko kukuthi, iinguqulelo ezine zemfuza efanayo. Enye yazo ixhaphake kakhulu kuhlobo lweManx; olunye uhlobo lwePixie Bob; kwaye kukrokrelwa ukuba enye ingunobangela womsila omfutshane we I-American Bobtail kunye nenye evela Kurilian Bobtail.
Kuxhomekeke kwinqanaba labo lokungena, abo banoboya baya kuba nomsila omfutshane okanye ongaphantsi. Olunye uluvo olufundwayo kukuba iikati ezizalwe ngokwendalo zingenamsila zineenguqu ezingaziwayo.
Kodwa lo mfuza awunaxanduva lobude bomsila kuphela, kodwa nezinye izinto. Umzekelo, kwiManx inxulunyaniswa neziphene kwinkqubo ye-nervous system xa i-homozygous. Ngaphezu koko, iinjana ezi-homozygous zihlala zifa emva kokuzalwa. IiHeterozygotes, kwelinye icala, zinokuzalwa ngaphandle komsila okanye ngomsila okhethekileyo, kodwa zihlala zikhubazekile ngasemva.
Ngokuchasene noko, kwiindawo ezahlukeneyo, ngakumbi iAsia neRussia, kuye kwafunyanwa iikati ezingazaliyo ezizelwe ngaphandle komsila ogama ufuzo "T" olungadibaniyo nakuphi na ukukhubazeka okanye isifo.
Kwaye wena, ukhe wazibona iikati ngaphandle kwemisila? Ucinga ntoni ngalo mbandela?
