Gerbils in the wild are called golden agouti. The genetic code is AACCEEDDGGPP with no recessives.
The letters used to represent genetic codes are called
alleles. When writing a gerbils code, write the letters in alphabetical order. If the second allele of a pair is unknown, write an * or -. The dominant alleles are capital letters while the recessive are lower case.
A white belly
aa solid belly
Ccb or Cch only affects coat color if the animal is ee or pp
cbcb or cbch = colorpoint (lighter body, darker tail and nose)
ch caused more lightening than cb
chch is a dark tailed white (if pp then Pink Eyed White, no matter what other recessives are present)
cb = the eye is a “wine” color. It looks black until light shines into it, and then it has a ruby color.
E lower
band is black on the hair shaft
ee lower band is honey colored (DEH)
efef = schimmel (pups start out orange, fading to cream with orange tail and nose, similar
to the colorpoint gene)
eef gerbil will have lightened/orangish tint to coat
G controls the
yellow middle of hair shaft
gg turns this part to gray
P controls the
color of the gerbils eyes. It also affects both black bands of the hair shaft.
P has black eyes along with normal black banding.
pp = red or ruby eyes and banding turns grey (argente is an offshoot
of the golden agouti.
Sp causes spots.
Sp gene affects animals with ee like the Dark Eyed Honey and Nutmeg which will be lightened
SpSp is a lethal combination
spsp is a normal colored gerbil
