Cov xim dab tsi yog miv

Cov miv hauv tsev txawv ntawm lwm cov tswv cuab ntawm tsev neeg miv hauv ntau yam xim. Tsuas muaj ob lub pigments koom nrog hauv kev tsim cov xim: dub thiab daj (nyob rau hauv lub neej txhua hnub nws yog hu ua liab). Cov xim dawb ntawm lub tsho tiv no yog vim tsis muaj xim xim.

Yuav ua li cas nws ua hauj lwm

Nyob rau hauv ib khub ntawm cov noob lub luag hauj lwm rau cov xim, ob hom tseem ceeb, ob hom recessive, los yog ib qho kev sib txuas ntawm ob qho tib si tuaj yeem ua ke. Cov noob "Dub" thiab "dawb" yog cov tseem ceeb, "liab" - recessive. Txawm tias muaj tseeb hais tias nyob rau hauv ntau yam ua ke lawv tsim tsuas yog rau khub, qhov teeb meem yog nyuaj los ntawm lub hav zoov ntawm derivative xim.

Ib tug ntshiab xim yog tsim los ntawm tusyees faib round pigment hais. Tib tus nqi ntawm cov xim tuaj yeem muab faib ua cov Islands tuaj lossis txo qis vim yog cov duab elongated ntawm cov khoom. Nyob rau hauv thawj rooj plaub, ib tug xiav xim yog tau los ntawm ib tug dub pigment, thiab ib tug cream xim los ntawm ib tug liab. Qhov kev xaiv thib ob yog ib txwm rau cov xim dub thiab muab cov xim chocolate.. Derived (diluted) xim nthuav cov txheej ntawm noob variations. 

Tab sis tsis yog txhua yam! Ntxiv nrog rau cov xim dilution, muaj lwm yam kev txiav txim siab caj ces (mutations). Ib tug ntawm lawv yog agouti, vim hais tias cov ntaub plaub yog dyed nrog kab txaij. Tsuas yog ib qho xim tau koom nrog hauv qhov no - dub. Tsaus thiab lub teeb kab txaij yog tsim los ntawm ntau qhov sib txawv thiab cov xim ntawm cov plaub hau tib yam. Yog li ntawd, xim av, apricot lossis daj-xuab zeb kab txaij tuaj yeem tsim. Thiab txawm hais tias keeb kwm cov xim agouti hu ua daj-striped, nws yog tsim tshwj xeeb los ntawm cov xim dub..

Yog li ntawd, felinologists tsis paub qhov txawv ntawm peb hom, tab sis tag nrho pawg ntawm cov xim. Nyob rau hauv txhua tus ntawm lawv muaj kev hloov pauv nyob ntawm kev sib xyaw ua ke thiab kev faib cov pigments. Thiab yog tias koj hla tus miv thiab tus miv uas nyob ntawm ntau pawg, tsuas yog tus kws tshaj lij geneticist uas muaj kev paub dhau los tuaj yeem kwv yees qhov tshwm sim. Thaum kawg ntawm lub xyoo pua nees nkaum, ntau tshaj 200 miv xim tau paub, thiab qhov no tsis yog qhov txwv.

7. Bicolor. Ib qho ntawm cov xim dhau los ua ke nrog cov pob dawb.

Yog tias koj saib ze rau ntawm daim ntawv teev npe no, nws yuav pom tseeb tias cov miv tricolor kuj yog cov bicolors, uas yuav tsum tau hu ua tricolors. Lawv tsis tshua muaj thiab nyob rau hauv ntau haiv neeg raug suav hais tias coj kev zoo siab thiab hmoov zoo. Tab sis yog tias koj hlub koj tus tsiaj, ces koob hmoov yuav tsis tso koj tsis hais nws cov xim.
