Headspot (Star)

 

 

Description

 

A headspot or star is a white mark on a rat's forehead, usually located in the middle of the forehead between ears and eyes. Shape can vary greatly, from triangular, irregular, or round. This marking is never seen on a self rat - only on rats with other markings on the body, the more marking, the more likely to have a headspot.

 

Genetics

 

Facial markings are believed to be the result of a modifier on the Hooded (H) locus, but are not genetically described. There are believed to be multiple genes controlling these markings. Some are the result of white-spotting genes and may lead to an increased chance for megacolon, therefore they should only be bred from known lines, and with care..

AFRMA
