What the Heck is this Color?

 


 

Ever have one of those "What the heck is this color, anyway" colored pups or dogs?

There is an explanation: it could be caused by an Incomplete dominance or Codominance of the genes.

INCOMPLETE DOMINANCE:

The situation in which both alleles of a heterozygote influence the phenotype. The phenotype is usually intermediate between the two homozygous phenotypes. The situation in which a heterozygote shows a phenotype somewhere (but not exactly half-way) intermediate between the corresponding homozygote phenotypes. (Exact intermediacy is no dominance). Simply: lightens the dark color and darkens the light color --- ex. pink roses (not red, not white).

CODOMINANCE:

The situation in which a heterozygote shows the phenotypic effects of both alleles equally. Simply: a blending of colors --- ex. would be Clay (not black, not cream).

Clay

As a puppy, he exhibited a darker color down his back and on his tail (as did his brother Cider -- see him on the "Mismarked" page).
He began to lose this odd coloration around 4 or 5 months old.
When he shed his winter coat, the black hair re-appeared.
The picture doesn't do him justice; because his color is beautiful --- his coat hair color is an array of cream, sorrel, orange, butterscotch, brick red looking hair color.
