The Fun Mouse: Varieties: Rex
 |
Rex
Symbol: Re
Chromosome: 11
Inheritance: Dominant
Description: You can tell if a mouse is going to be rex when the whiskers come in at or slightly after birth. Whiskers will be curly or crimped. When the fur grows in, it will have a noticeable wave. As a rex mouse ages, the fur will straighten out a little to a lot. There are 3 visual stages to the rex coat. As youth the coat is very curly. As young adults the coat straightens out to the point that the fur usually stands on end. As adults, some rex mice have a nice, soft wave to the coat while others only have slightly waved guard hairs. Well bred rex mice will keep their wavy coat thru life.

Homozygous Rex Re/Re tend to have better curl. Rex can show all other coat types as well (Satin Rex, Angora Rex (Texel), Frizzy Rex (tho this is harder to notice in appearance), etc).
Breeding: Because Rex is Dominant, you can get Rex babies by breeding only one Rex parent to anything. Mice that have Rex in their background, yet are not Rex themselves, will not have Rex babies. Homozygous Rex (having both Re alleles) tend to have better curl. In addition, combining Frizzy with Rex also tends to give better curl. In my experience, combining Frizzy and Rex makes younger mice have spiral-like curls and holds curl better with age.
Breeding inheritance
Homozygous Rex Re/Re x Homozygous Rex Re/Re =
- 100% Homozygous Rex Re/Re. Showing Rex Coats.
Homozygotes Rex Re/Re x Heterozygous Rex Re/re =
- 50% Homozygous Rex Re/Re. Showing Rex Coat.
- 50% Heterozygous Rex Re/re. Showing Rex Coat.
Heterozygous Rex Re/re x Heterozygous Rex Re/re =
- 50% Heterozygous Rex Re/re. Showing Rex coat.
- 25% Homozygous Rex Re/Re. Showing Rex coat.
- 25% Standard re/re. Not showing Rex coat.
Homozygotes Rex Re/Re x Standard re/re =
- 100% Heterozygous Rex Re/re. Showing Rex Coat.
Heterozygous Rex Re/re x Standard re/re =
- 50% Heterozygous Rex Re/re. Showing Rex coat.
- 50% Standard re/re. Not showing Rex coat.
Problems: No health abnormalities reported by labs. I have, however, found that curlies tend to get "nest box eye" (aka "weepy eye") more often than non-rex mice. I find it happens more with texels than rex. Babies sometimes have this just after their eyes open. Sometimes it happens again in late adulthood. Generally wiping it out with warm water 2+ times a day will clear it up no problem. All it seems to be is a gunk build up. |
