Ok, so I'm going to tryyyyyyy to post my understanding of genetics, but PLEASE feel free to post better information. Black= aa M- R- P- Agouti= A- M- R- P-These are the two main colours, other colours are dilutes of either of these. If the colour has an A (agouti) gene present it will cause the hair to be ticked, if it has aa (black) present, it will not be ticked, therefore the hair will be all one colour. Cinnamon= A- mm R- P- : Therefore a dilute of agouti. Argente= A- M- rr P- Silverfawn= A- M- R- pp Mink= aa mm R- P- : Dilute of black. Beige/Buff= aa M- rr P- Champagne= aa M- R- pp Two or more present dilute genes: Topaz/Fawn= A- mm rr P- : Agouti dilute. Dove= aa mm rr P- : Black dilute. (- represents the hidden genes that are carried. ie: Agouti may carry black, Aa M- R- P-, if not it will be AA M- R- . Okok. I guess I should post abit about what each gene does.. A-/aa= A- (dominant) causes banding of the hair, aa (recessive) causes no banding. M-/mm= M- (dominant) causes no change in coat, while mm (recessive) dilutes. R-/rr= R- (dominant) causes no change in coat, rr (recessive) causes dilution of the coat, and dilutes the eye colour to ruby (dark red). P-/pp= P- (dominant) causes no dilution of the coat, while pp dilutes the coat and the eye colour to pink. I learnt all this information from September Skies Rattery. Good luck : D

Ok can we please try and keep to the AusRFS standards. Beige is more commanly refered to as BUFF. It is refered to as beige more commonly in the USA.
I have had it explained to me that cinnamon and mink are not actually dilute of agouti and black but ARE ahouti and black with the mink gene mixed in. Also it may confuse newbies when you refer to dove being dilute of black when it is in fact the dilute of MINK.
OK now I'm looking oicky BUT you have the colour codes wrong on a couple of the colours Argente = A- mm-rr-P- its the dilute of cinnamon Fawn = A-M-rr-P- its the dilute of agouti.
SO can I show you how it was set out for me (I'll assume you say yes LOL)
Ticked Coats Agouti A-M-R-P- (black eyed base for ticked) Fawn A-M-rr-P- (ruby eyed dilute of agouti) Silverfawn A-M-R-pp (pink eyed dilute of agouti)
Ticked Coat with Mink gene added Cinnamon A-mm-R-P- (black eyed agouti with mink gene) Argente A-mm-rr-P- (ruby eyed dilute of cinnamon)
Non Ticked Coats Black aa-M-R-P- (black eyes base for non ticked) Buff aa-M-rr-P- (ruby eyed dilute of black) Champagne aa-M-R-pp (pink eyed dilute of black)
Non Ticked Coat with Mink gene added Mink aa-mm-R-P- (black eye base with Mink gene) Dove aa -mm-rr-P- (ruby eye dilute of Mink)
Ok I'm done now :-)

I must pay attention to this thread, after 8 years of breeding rats I still don't get it

I know punnet squares, kinda, we learnt that at TAFE. But the whole coding thing has never sunk in. But then, it's never been explained the way you did, so thanks for dumbing it down

well it takes a dumby to explain it simpley hehe. You want to know how I got it to stick in my head? I wrote it out just like that and added it to a photo that I then used as the wall paper to my PC. as I'm here every night I'd look at it and it stuck in my head eventually. Till then I think i was doing Pixies head in when I got it wrong hehehe

Blue is symbolized as gg or the carriers as G- Every colour CAN carry blue if they are crossed with a blue rat so its just a case of adding the G- to their colour code if blue is in fact in their blood. ie: an agouti carrying blue is A-M-G-R-P a blue agouti would be A-M-gg-R-P-
edit to make it a bit clearer as I did write it a bit misleadingly

so dose that mean that every agouti has a blue in them and if you have a colony of agoutis to gether 1 in 20 could be a blue
