Nws tuaj yeem hais tias ib qho ntawm cov cim tshaj plaws ntawm cov dev yug hauv ntiaj teb yog ciam teb collie, ob qho tib si rau nws txoj kev txawj ntse thiab kev zoo nkauj. Muaj tseeb tiag, thaum koj xav txog hom no, tus dev dub thiab dawb tuaj rau hauv siab sai sai, txawm li cas los xij, muaj ntau hom ciam teb collies nyob ntawm cov xim ntawm lawv lub tsho.
Hauv kev muaj tiag, ntau yam ntawm cov tsiaj no muaj ntau heev, suav nrog cov merle version ntawm yuav luag txhua yam xim, uas tshwm sim vim muaj cov noob uas encodes muaj cov xim sib txawv ntawm merle coats. Hauv tsab xov xwm no peb qhia koj tag nrho cov ciam teb collie xim thiab piav qhia vim li cas lawv tshwm sim.
Txais xim hauv ciam teb collie
Ib qhov tseem ceeb tshaj plaws xav paub ntawm ciam teb collie yog nws ntau yam xim, vim qhov no yog txiav txim los ntawm nws cov noob caj noob ces. Ua raws li ciam teb collie yug tus qauv kos los ntawm International Cinological Federation (FCI), tag nrho cov xim uas peb yuav nthuav dav hauv qab no tau txais. Txawm li cas los xij, cov xim dawb, vim yog vim li cas majeure, yuav tsum zam, raug cais tawm ntawm tus qauv.
Tag nrho cov xim mus rau ib txheej uas ib txwm dawb, yog cov tricolor cov qauv uas nthuav tawm txawv variations nyob rau hauv ua ke ntawm cov cov suab hauv qab no: liab, dub thiab dawb. Yog li, nyob ntawm caj ces, cov xim no yuav nthuav tawm ib lub suab los yog lwm qhov, raws li peb yuav qhia rau koj tam sim ntawd.
Border Collie Color Genetics
Cov xim ntawm lub tsho tiv no, qhov muag thiab tawv nqaij nws tus kheej yog txiav txim los ntawm cov noob sib txawv. Nyob rau hauv cov ntaub ntawv ntawm ciam teb collie, tag nrho ntawm 10 noob ncaj qha koom nrog pigmentation tau raug txheeb xyuas, uas melanin yog lub luag haujlwm. Melanin yog xim xim uas muaj ob chav kawm: pheomelanin thiab eumelanin. Pheomelanin yog lub luag haujlwm rau cov pigments uas mus ntawm liab mus rau daj thiab eumelanin rau cov uas mus ntawm dub mus rau xim av.
Tshwj xeeb, ntawm 10 cov noob no, 3 yog cov txiav txim ncaj qha ntawm cov xim xim. Cov no yog cov noob A, K thiab E.
- Gen A: Yog hais tias nws yog Ay allele, tus tsiaj muaj lub tsho tiv no ntawm daj thiab liab, thaum nws yog At, muaj ib lub tsho tricolor. Txawm li cas los xij, qhov kev qhia ntawm gene A nyob ntawm qhov muaj lossis tsis yog ntawm ob lub noob, K thiab E.
- Gen K: nyob rau hauv cov ntaub ntawv no, muaj peb yam alleles. K, ua qhov tseem ceeb, tiv thaiv kev qhia ntawm A, ua rau muaj xim dub. Yog tias nws yog Kbr allele, A tau tso cai los qhia nws tus kheej, ua rau muaj xim nyob rau hauv uas ib hom kab txaij tshwm nyob rau hauv cov xim daj-liab uas muab lub tsho tiv no rau brindle. Thaum kawg, nyob rau hauv cov ntaub ntawv ntawm recessive gene k, A kuj qhia, yog li ntawd tus yam ntxwv ntawm K tsis nyob. Raws li tshwm sim nrog gene A, gene K nyob ntawm gene E rau nws qhia.
- Gen E: Cov noob no yog lub luag haujlwm rau eumelanin, yog li yog cov tseem ceeb allele E tam sim no, ob qho tib si A thiab K. homozygous recessive allele (ee), kev qhia ntawm eumelanin yog tiv thaiv, tsuas yog pheomelanin nyob rau hauv cov dev.
Tab sis qhov kev qhia ntawm cov noob loj no tsuas yog piav qhia cov xim hauv qab no xwb: Australian Liab, Dub, Xuab zeb, thiab Tricolor.
cov noob caj noob ces nyob rau hauv ciam teb collie xim
Ntxiv rau 3 cov noob tseem ceeb uas tau hais los saum toj no, muaj tag nrho ntawm 5 cov noob uas cuam tshuam thiab hloov kho xim hauv ciam teb collie. Luv luv, cov noob no yog:
- Gen B: muaj cov teebmeem ntawm eumelanin. Qhov tseem ceeb ntawm allele B yog suav tias yog ib txwm, thaum b hloov xim ntawm dub mus rau xim av.
- Gen D: cov noob no cuam tshuam qhov kev siv ntawm cov xim, ua raws li ib tug diluent ntawm tib yam nyob rau hauv nws recessive version d, kom nws hloov dua siab tshiab, piv txwv li, dub rau xiav lightens daj thiab liab thiab ua rau xim av lilac.
- Gen M: zoo li D, noob M nyob rau hauv nws cov dominant allele ua rau cov xim dilution, muaj cov nyhuv ntawm eumelanin. Hauv qhov no, dub yuav tig mus rau merle xiav thiab xim av rau merle liab. Cov tsos mob ntawm homozygosity ntawm cov noob tseem ceeb (MM) yog cov qauv ntawm cov noog dawb dawb, uas tsis muaj xim, tab sis qhov kev txhawj xeeb tshaj plaws yog tias lawv muaj teeb meem kev noj qab haus huv, xws li dig muag lossis tsis muaj qhov muag, lag ntseg, thiab lwm yam. tej yam kev mob. Vim li no, tus ntoo khaub lig ntawm blackbird specimens raug txwv los ntawm lub koom haum thiab lawv tiv thaiv kev sau npe ntawm cov hom ciam teb collie txhawm rau kom tsis txhob nthuav tawm cov tsos ntawm cov tsiaj no, uas yuav raug kev txom nyem ntau thoob plaws hauv lawv lub neej, ib yam dab tsi tshwm sim hauv albino. dev. nquag heev.
- Gen S: muaj 4 alleles ntawm no noob, lub luag hauj lwm rau kev qhia cov xim dawb nyob rau hauv tus tsiaj lub tsho tiv no. Nyob rau hauv cov ntaub ntawv ntawm cov tseem ceeb allele S, dawb yuav luag yuav luag tsis tuaj, thaum nyob rau hauv sw, feem ntau recessive ntawm tag nrho cov, tus tsiaj yuav dawb kiag li, tshwj tsis yog rau ib co yuav luag cais me ntsis ntawm cov xim ntawm lub ntsej muag thiab lub cev thiab lub qhov ntswg, uas kuj. yuav qhia xim.
- Gen T: Cov recessive t allele yog qhov qub thiab T ua rau cov xim variegated tawm, uas tsuas pom thaum tus dev twb muaj hnub nyoog lawm.
Kev sib xyaw ntawm tag nrho cov noob no tau piav qhia tag nrho cov xim ntawm ciam teb collie, uas peb nthuav dav hauv qab no.
Txhua tus ciam teb collie xim: hom thiab duab
Cov caj ces sib txawv ua rau muaj ntau qhov sib txawv ntawm cov xim ntawm ciam teb collie, nrog rau ntau lub tsho loj.

Tsis zoo li xiav merle, slate merle muaj lub qhov ntswg dub thiab feem ntau tsaus grey lossis xiav ob lub qhov muag. Tsis tas li ntawd, cov xim ntawm lub tsho tiv no feem ntau yog sib dua.
Australian Liab Ciam Teb Collie los yog Ee-red
Cov yam ntxwv tseem ceeb ntawm Australian liab ciam teb collie yog cov xim no feem ntau tshwm sim npog lwm cov xim thiab tshwm sim hauv blonde tones sib txawv Lub hauv paus xim tuaj yeem pom los ntawm kev saib ntawm lub qhov ntswg thiab daim tawv muag, txawm hais tias qhov no tsis yog ib txwm ua tau, yog li tsuas yog txoj hauv kev kom paub meej tias lub hauv paus xim yog los ntawm kev kuaj caj ces. Nyob rau hauv txoj kev no, hauv Ee-liab ciam teb collie, liab tshwm rau saum lwm cov xim uas tsis tuaj yeem pom nrog lub qhov muag liab qab, suav tias yog xim xim, vim li no cov hauv qab no ciam teb subtypes yog txawv australian liab. collie:
- Ee-red negro: with a black base color and a ruby red color uas npog nws.
- Ee-red chocolate: Liab yog nruab nrab, tsis khaus heev los tsis dhau.
- Ee-red azul: with a blue undercoat and a blonder red.
- Ee-red merle: qhov no yog qhov kev zam ntawm kev muaj peev xwm paub qhov txawv xim xim ntawm daim ntawv commented, txij li thaum lub saib merle-based australian liab ciam teb collie zoo li liab yog xim tawv. Tsuas yog los ntawm kev siv cov tshuaj ntsuam genetic test nws thiaj paub tseeb tias nws yog Ee-red merle ciam teb collie.
- Ee-liab sable, lilac lossis xiav: Txawm tias tsawg dua, kuj tseem muaj cov qauv uas Australian liab qhov ncauj qhov ntswg rau cov xim no.
White ciam teb collie
Raws li peb tau hais ua ntej lawm, tus dawb ciam teb collie yug los ntawm qhov muaj ob hom tseem ceeb ntawm M noob. iris pigmentation. Tab sis, cov tsiaj no muaj kev noj qab haus huv heev, nthuav tawm cov teeb meem kev noj qab haus huv loj uas cuam tshuam rau lawv lub cev tag nrho, los ntawm qhov muag tsis pom kev mus rau daim siab lossis teeb meem plawv, thiab lwm yam. Vim li no, kev hla ntawm ob lub merle specimens raug txwv los ntawm feem ntau cov koom haum canine, vim muaj peev xwm yug me nyuam ntawm dawb ciam teb collie menyuam dev, uas yuav nqa cov teeb meem no thoob plaws hauv lawv lub neej.
Ntawm qhov tod tes, peb nco ntsoov koj tias dawb tsuas yog Border Collie xim uas tsis tau txais los ntawm FCI. Yog li, txawm hais tias nws yog ib hom ciam teb collie uas muaj, raws li peb hais, nws tsis pom zoo kom rov tsim dua.
