Rex
Rex, Re/re
One copy of the semi-dominant Rex
Chromosome: 7
RVG description:
Rex presents with a typical rexoid or curly phenotype. The vibrissae are short and bent. The hairs of the coat are shorter than normal and curled, giving the coat the characteristic "curly" appearance. Waving is present in young rats between the ages of 1 to 3 weeks; thereafter, the coat may appear woolly. The coat feels soft due to the lacking guard hairs and any rough texture that develops progressively through adolescent and adult moults will be due to existing guard hairs. Rex usually have a good covering of hair although the skin should be visible as the curls will clump together exposing slivers of skin. Several individuals have been observed with distinctly thinner coats as well as fully coats.

The following pictures are of subpar Rex coats as these do not live up to the show standard. They are too "fluffy" and the curl is lose and not defined.
