OK Folks...I know that a lot of folks have wondered just WHAT color that boy REALLY is...so we sent off to UC Davis for testing, and the results are in!

Red-Factor Result:
E/e - Both black and red factors detected. Either E or e transmitted to offspring. Basic color is black, bay or brown in the absence of other modifying genes.

Agouti Result:
A/a - Black pigment distributed in points pattern. Basic color is bay or brown in the absence of other modifying genes.

Cream Result:
N/Cr - Heterozygous, dilute, one copy of Cream gene. Typical colors are palomino, buckskin and smoky black in the absence of other modifying genes.

So what does this mean?  Romeo is a buckskin (Bay base coat with cream dilution). 

What does that mean his babies could be colored like?  Here's a link to a pretty informative site for color factors:
