But I am definitely hoping to learn more!
from what i learn is some grow hair in spots, then it falls out then grows other places... kind of cycles like that, where as a double rex just is bald with some having a few straggler hairs.... i think, not sure thou
Re: Double Rex aka Patchwork Genetics
I'm really not a 100% sure, but I found this (which is pretty what I keep coming accross on the net, but doesn't mean it's the absolute truth):
"Patchwork hairless rats maintain a certain amount of short, soft fur on their bodies and patches where they are bald. The fur will periodically fall out and grow back in throughout the rat's life in different patterns. They usually maintain whiskers though they are generally brittle and curly. While they are more prone to allergies, they are hardier than the true hairless rats and should live an average lifespan. The females also have no problems reproducing or raising litters. There are three strains of patchwork hairless rats:
1) Double rex: produced from two rex-coated parents (ReRe). Different from the other two strains as they tend to keep some fur on the face, head, feet and ankles while maintaining a mostly hairless body. If bred to a normal-coated rat they will produce rex-coated pups. If bred to a rex or velveteen-coated rat they will produce double rex pups.
2) Double Velveteen: produced from two velveteen-coated parents (CuCu). If bred with a normal-coated rat will produce velveteen-coated pups. If bred to a velveteen or rex-coated rat they will produce double velveteen pups.
3) Double velveteen/Double rex: produced from one double rex-coated parent and one double velveteen-coated parent (CuCuReRe). If bred to a normal-coated rat they will produce rex-coated and/or velveteen-coated pups."
