Non-extension Red
E LOCUS:

The dominant form, "E", is normal extension (which will result in a black coat, if no
other modifiers are present). The recessive form, "e", is non-extension. When a
dog is homozygous for non-extension (e/e), its coat will be entirely red or yellow
(phaeomelanin based) with no eumelanin production (void of any black hairs).

A dog with the non-extension gene (e/e) present, that is black (B/B or B/b) will
have a yellow to red coat and black skin pigment on the nose, eye rims and lips.

















A dog with the non-extension gene (e/e) present, that is also brown (b/b) will
have a yellow to red coat with brown skin pigment on the nose, eye rims, and lips.


















A dog with the non-extension gene (e/e) present, along with a dilution gene ("d")
may be pale yellow to white in color.
If two red's (cream) are mated, the entire litter should be cream colored.  The
way to produce the cream color from any other color, besides cream, is to make
sure that
both parents carry the non-extension allele ("e").   Example:  it is
possible to produce the cream color from two black dogs, however;
BOTH
parents must
carry the non-extension allele ("e").
