Taw qhia: Qhov Tsis Paub ntawm Dawb Luav Fur
Cov xim ntawm luav plaub tuaj yeem sib txawv heev, xws li dub mus rau xim av, grey, thiab txawm xiav. Txawm li cas los xij, ib qho ntawm cov xim zoo nkauj tshaj plaws yog xim dawb. Cov luav dawb tau nrhiav ntau heev, thiab lawv cov plaub tau siv rau ntau pua xyoo hauv kev lag luam textile. Tab sis dab tsi yog vim li cas rau lawv cov xim txawv? Hauv tsab xov xwm no, peb yuav tshawb txog cov noob caj noob ces thiab biology tom qab luav lub tsho xim xim, nrog rau kev tsom mus rau cov xim dawb-plaub phenotype.
Cov Genetics ntawm Rabbit Coat Xim
Cov xim luav yog txiav txim siab los ntawm cov txheej txheem ntawm caj ces, nrog rau qhov muaj lossis tsis muaj cov xim sib txawv, qib ntawm melanin ntau lawm, thiab kev qhia ntawm ntau yam noob. Nyob rau theem pib tshaj plaws, muaj ob lub ntsiab ntawm cov xim uas ua rau cov xim luav: eumelanin thiab pheomelanin. Eumelanin yog lub luag haujlwm rau cov xim dub thiab xim av, thaum pheomelanin tsim cov xim liab thiab txiv kab ntxwv. Qhov sib npaug ntawm cov xim no, nrog rau lawv qhov kev faib tawm thoob plaws hauv cov plaub, tuaj yeem sib txawv ntawm cov luav ntawm ntau hom thiab cov keeb kwm caj ces.
