One of a few things has likely happened. Keep in mind that the simplest explanation is usually the most accurate.
A) Your standard coated mice are actually very poor angoras who don't show any length at all
B) One or both of the original texels is actually just Ca/* and/or Re/* with no go/go
C) You're dealing with both go/go and lgh/lgh
A and/or B are the most likely.
If you breed 2 different curlies together with different genetic background you'll get nomal coats.
This isn't true. For example, homozygous Caracul mated to homozygous Rex will give all curly coats. Actually, either of them mated to anything will give all curly coats!
When I was a kid people would always ask me where I got my eyelashes from...like how would I know?
I would have said something like "Walgreens."
