Hypothesis:

I had a hypothesis that the golden gene was pink or red eyed dillute poorly expressed on the black eyed gene because it yields very little color. This was backed by my difficulty getting RED or PED to express on Burmese and the fact that RED can be thought of as an incomplete dominant since it will fade a rat significantly with one copy. This is matched by the golden gene being easy to identify with one copy, on recessive c loci, due to it being more yellow than a regular siamese but not as golden as two copies.

Experiment:

I paired a golden siamese male with a female genetically homogeneous for PED and RED (I have an entire line if these). The litter size is 13 which is quite a significant sample size. The litter is just developing fur and it is apparent each in the litter is agouti. A few look lighter but it could be due to development so I'll monitor them. But it is safe to say I was expecting 100% PED or RED so it can be unequivocally said that Golden is not related to either eye dillution.

No, it's not a bad black. These are tonk burmese. You can barley see the points. 30k lumens to show points.

Should have been a litter of all Amber (Silver Fawn). Will repeat to remove any uncertainty.

6 Amber
1 Champaign
3 Agouti?

Having trouble distinguishing Agouti from Wheaten Burmese. The ratio suggests these are Burmese though. Getting closer to definitively identifying Amber Burmese.

The Golden Gene is a rare gene that only expresses when present with the black eyed gene and agouti.

I believe that the black eyed gene is a shading gene on the burmese locus. I believe that albino, RED, and PED work on hair pigments in similar ways. While Burmese/BE only expresses on rats homogeneous for recessive c loci, it may be that PED and RED are extremely covered too by the Burmese/BE gene when also present on a rat homogeneous with a recessive c locus. My breedings suggest golden may just be RED or PED and only a bit of red shows through. More testing to come to prove it. But it would make sense why agouti needs to be present.

From breedings I firmly believe Burmese and the Black Eyed Gene are on the same locus.

Bu: Burmese
Bu(be): Black Eyes
bu: Red Eyes (unexpressed)
