A Chocolate Tan Dog carries the Gene Formula (aybCDEgmrSt).
This color is recessive in nature and will re-produce itself Only when
bred to a dog that is the same color or to one that carries the chocolate
(b) gene and the tan (ay) gene. The Tan (ay) gene and the chocolate (b)
gene must be present in double dose in order for the offspring to
be this color. It can range from a light Tan to a milk chocolate color
and will always have a nose to match the color of the coat and never black.
It is called chocolate tan only to distinguish from the base color coming
from the tan color as opposed to the underlying black or (A) gene of a
chocolate/liver dog.
It can also be confused with the color called Apricot. Although it
may look this color in genetic formula it differs greatly and will not
reproduce in the same manner.
If this dog also has white on the coat it means that the (S) gene would
be replaced with one of these White producing gene patterns, (si,sp, or
sw) in any combination. For more info see White
Chart.
