TERMS - 


tyrosinase-related protein-1 (TYRP1) gene 

Melanin - is simply put pigment of any kind

Eumelanin - is the pigment responsible for blacks and browns in mammals

Phaeomelanin - is the pigment responsible for reds and creams/blonds and in cats is found on the X chromosome, meaning it is sex linked.





Email from Dr. Leslie Lyons regarding coat color/pattern inclusion when queried regarding various coat colors/patterns.


Hello Lucy,

 I think your thought process matches mine on this matter.  One thing, red and silver were more likely to be widespread in cats whereas brown/cinnamon were more likely of Asian origin – as you said – and more rare.  Genetic testing can help anyone monitor a color – any color and pattern – so if someone does not want it – just test your breeding stock.  Limiting colors and lines could limit genetic diversity.

 I would rather the Siberians put in mandatory genetic testing for health issues than for colors and such. 

 Best regards,

Leslie
