Gerbil Color Table
Be
sure to read through the basic genetics page if you don't already
have an understanding
of that material, otherwise this page will be completely
meaningless to you.
Use this table to find out the possible gene combinations in your gerbils' genomes. The Color Names in blue cells are the basic colors. The Colors Names in any other colored cell are created with variations on the albino locus C, which includes lightened forms and Colorpoint varieties. To find a color using a specific gene combination, first look down the right hand side to find the combinations of homozygous genes your gerbil has. Then move over to the color area (Light - aqua, Colorpoint - green, Light Colorpoint - lime) containing the combination of genes on the albino locus (C, cb/h, etc), and finally to either the Agouti or Self Column within each color Area. You could also This might sound complicated at first, but once you get it, it'll be a breeze. Read through an Example.
Note: This table contains colors which are possible using combinations of genes found in the United States. There is another locus (the Dilution locus) which can hold the recessive gene d, which has the affect of diluting the overall color of the fur. This gene, however, is only extant in European stocks. Visit ___ for more information on this new gene. I wil also be adding the ef varieties at a later date.

Some Notes:
Any chch gerbil will be a Dark Tailed White (DTW) if it
is P*.
A DTW will theoretically have a darker tail if it is self
(think of it as a really colorpoint black instead of a really
colorpoint agouti - the tail will turn self, instead of agouti,
making it darker)
Any c*c* gerbil that has pp as well will be a PEW
Its good to note that e is not entirely recessive, and
will show partially in some individuals. Ee Golden Agoutis might
possibly have more red in their fur, it has also been mentioned
on the AGS List that Gg Burmeses are intermediate between GG
Burmeses and gg Colorpoint Slates.
Example Color Identification using known gene combinations:
Lets say you have a breeding pair of gerbils with the following genes
aaCCEEGGPp (Black) and AaCCEEGGpp (Argente Golden).
Using your brain, a piece of paper and a pencil, and knowledge of Mendelian genetics, you find that the offspring will all be CCEEGG, since there are no other combinations possible. So, you can disregard those for now. The possible combinations we have left are:
AaPp, aaPp, Aapp and aapp (all with CCEEGG, of course).
We'll use the AaPp pup as an example - we'll name him Rover. Look at the right hand side of the table. Rover has none of the homozygous recessive gene combinations in this column, so we'll stick to the row labeld 'NONE'. Now - Rover does not have any C recessives, so we will stick to the basics color area (blue). Rover has the combination Aa, so we look at the A* agouti column. Voilá! We've narrowed our search down to one cell. Rover turned out to be a Golden Agouti (his full genetic make-up is AaCCEEGGPp). Do the same thing for the remaining three offspring possibilities - if you do this correctly, you'll find that the aaPp, is a Black, the Aapp is an Argente Golden and the aapp is a Lilac.
