i bet if you bred him to a rex showing female, or even bred back to babies of normal female, babies showing rex, offspring might come out hairless. hehehe mine did, was odd but desired on first try luck. now trying to breed down dwarfs or pygmies whatever you want to call, as had female come out tiny and only baby to survive as was biggest, so bred her back to father and got even tiner healthy babies, but sadly i culled the male, for some reason, before could tinker more with his genetics, but his raccon marked boy (was largest male, and maybe not right choice, but so darn pretty and such silkie hair!), might be promising, with his grand daughter (only female out of litter). anyone know how to look for, find or encourage the tailless gene t show up, or what to look for to get it? all i get are half tails except two long ago, who died as pups. want to breed tiny baby pinkie rats for baby snake food, so no more darned trying to breed stinky stupid mice (though loved breeding as child).
