Ruvara rwemaziso rwunopihwa ne Genetic nhaka, kana maziso aine hutano hwakakwana ane ruvara rumwe chete. Maziso evana vadiki anowanzo grey kana kuchena bhuruu muvara uye iri makore angangoita matanhatu negumi ekuberekwa kwechokwadi.
Kazhinji, vanhu nemhuka vane maziso e brown, nepo vashoma chete vane maziso ebhuruu kana girini. Chikamu cheziso chinoratidza ruvara chinonzi iris uye zviitiko zvinogona kuitika umo maziso ane rumwe ruvara rumwe, izvi Fani inozivikanwa seheterochromia. Uku kuremara kudiki kunowanzoitika mumhuka, imbwa, katsi uye kunyange mabhiza anogona kuve nemaziso akasiyana mavara imwe neimwe.
Mhando dzeheterochromia
Kune mhando mbiri dzeheterochromia dzinogona kuitika zvichienderana nezvikonzero zvinogona kuve zvichikonzera kukanganisa uku.
Chikamu heterochromia: ziso rimwe rine mavara emhando dzakasiyana.
Pedzisa heterochromia: maziso acho akasiyana zvachose mavara.
Kuberekwa heterochromia: izvi zvinoitika kana zvikagara nhaka.
Yakawanikwa heterochromia: inokonzerwa kana inogona kuitika nechimwe chirwere kana kushungurudzika.
Urema uhu hausi mamiriro anokanganisa kuona uye hazvisi zvakajairika kuti yakakwana heterochromia iitike mumunhu. Saka muchinyorwa chino tinotaura dzimwe mhando dzembwa dzine maziso maviri-mavara zvakasiyana, sevanhu vazhinji vanozviona zvichirova uye vanokwezvwa neichi chakakanganisika.
Muimbwa mune mhando dzinoverengeka dzinogona kuve neherterochromia yakakwana Tinogona kutaura pakati pavo pa Siberian Husky (Mune dzimwe nyika inozivikanwawo semhumhi yeSiberia nekuda kwekufanana kwayo neiyi hama yemusango), iyo Catahoula neAustralia Mufudzi.
Imbwa dzinobereka dzine chiitiko ichi mumaziso avo, kazhinji dzine ziso rebhuruu uye rimwe rakasviba uye ndezvekuti kana iris yeziso iri yebhuruu, inoitika kuburikidza ne Merle geneIri geni ndiro rinopa hunyanzvi uye zvakare rinoita basa rekukara mumhino dzembwa, iro rinonzi butterfly.
Nekudaro, inogona kuve chikonzero che chikamu heterochromia, semuenzaniso, zvishoma shava ruvara runogona kucherechedzwa mukati mebhuruu ziso ruvara. Tinogona kucherechedza Merle geni riripo mumhando dzakadai seAustralia Mufudzi, Border Collie uye Pembroke Welsh Corgi, uye izvi hazvireve kuti idzi shamwari dze canine hadzichanakidze vanhu, asi dzinovashandura kuita mhuka dzine hunhu pane mazhinji anogona kunge akasarudzika.
Nezve zvishoma heterochromia, kune mhando dzembwa dzinogona kuve nerudzi urwu rwehurema, mune rimwe ziso rine mavara maviri pamwechete, ndiko kuti, rinogona kuve rakasiyana-siyana. Pakati pavo tinogona kutaura Border Collie, iyo Pembroke Welsh Corgi, yeAustralia Sheepdog uye Great Dane.
Kana uyu musiyano wemuvara ukacherechedzwa mune iris yeimbwa dzinogadzirwa neMerle geni, zvinokonzerwa nekuti izvo izvi zvinoderedza pigmentationndiko kuti, kurasikirwa kwemavara kunoitika.
Dzimwe mhando dzembwa dzatingati dzinongoerekana dzave neHeterochromia ndiChirungu Cocker Spaniel, iyo Pit Bull Terrier, French Bulldog, iyo Boston Terrier uye iyo Dalmatia.
Kunze kwekutaura pamusoro pembwa idzo dzine maziso maviri akasiyana mavara uye nei izvi zvichiitika? Tinogona zvakare kutaura ngano dziripo nezveichi chiitiko chinoshamisa, sezvo zvaitendwa kuti imbwa idzi dzinopa dziviriro kuvanhu, maererano nenyaya. akasiyana mavara maziso (heterochromia) vaidzivirira vanhu, nepo avo vane maziso ebrown vakapa dziviriro kumidzimu.
Kune rimwe divi, Eskimos vaitenda kuti imbwa dzakateyiwa nehurema uhwu dzaigona kumhanya nekukurumidza.
