Siamese colourpoint

About the Colour

A mutation in the Colour gene (Tyrosinase, TYR) causes temperature sensitive pigment production.

The wild-type allele (C) is dominant and produces full colouration.

Two copies of the Siamese allele (cs) are required for Siamese colouration. The Siamese mutation restricts the pigmentation to the points.

Bengal and Savannah cats - our domestic cat Siamese colourpoint genetic test has also been validated in Bengal and Savannah cats (i.e. it will detect Asian Leopard Cat or Serval genes if they are present). 

Interpretation of results

Test Result Interpretation
Siamese colourpoint (cs/cs) Has two copies of the Siamese colourpoint allele (cs/cs)
Cat will have Siamese colouration
Carrier of Siamese colourpoint (C/cs) Has one copy of the Siamese colourpoint allele (C/cs)
Cat will have solid colouration
Does not carry Siamese colourpoint (C/C) Has no copies of the Siamese colourpoint allele (C/C)
Cat will have solid colouration

 

Mink Colour

Mink colouration is intermediate between Siamese and Burmese and is caused by the presence of one Siamese allele (cs) and one Burmese allele (cb). If you wish to test for Mink please select both the Siamese and Burmese colouration tests.

 

FAQs

How do I test for Snow colour in my Bengals?
