I've talked to many breeders about it, and apparently that can sometimes happen.
A lady in town who works at a pet store has a purebred registered yorkie who is 23lbs. Same thing happened to her. Her yorkie just grew unbelievably, and the littermates she said are right around the 5-6 lb range. So I don't know if that's what's called a throwback, but it's just something that is obviously there genetically. I think it's weird that one in the litter ends up growing like that and the others don't. I'd love to pick the brain of a geneticist and really get into the science and a thorough explanation for how and why this happens. |
maybe a recessive gene? would love to meet a 23 pound yorkie. lol.
