Colorado Rat Breeder | Camarattery

Website Updated June.10.2024

We do have babies available!
FYI...Please be aware that breeding season stops in July & August in the USA. Rats loose fertility in hot weather, so babies are scarce during that time. If you are going to adopt, now is the time. Breeding season doesn't really pick up again until the fall when the weather is cooler.

Marten Genetics

Amy of Camarattery 2.24.2016 ©


Martin is on the c-locus. But it cannot be Siamese. It only comes in Himalayan and Albino.

There are 3 types of Martens:

Albino = cc(m) or the non pointed Marten

Himalayan = c(h)c(m) which is also called the pointed Marten.

Homozygous which is Albino = c(m)c(m)

Martens can be Pink Eyed (because they are either a Himi or Albino), or UK Black Eyed. All you need to do is breed in the UK Black Eye gene to get BE. You can have Homozygous BE Martin which is 2 copies of the UK BE gene, or Heterozygous BE which carries one copy of the Pink Eye gene and one copy of the BE gene.

The genetics written out:

Agouti Marten Himi = Aa c(h)c(m) or homozygous Agouti is AA. Aa carries Black.
Black Marten Himi = aa c(h)c(m)

Agouti Albino Marten = Aa cc(m)

Black Albino Marten - aa cc(m)

Martens can come in any color for example a Russian Blue would be aarbrbcc(m) if its an albino Russian Blue or aarbrbc(h)c(m) for a pointed or Himalayan Russian Blue Marten. All colors would be written out the same way.

Martens can also be any pattern you want to breed them for.
