Hi Everyone, I am new here, saw this topic and had to post my color question…

So our younger Oldenburg stallion (Bay from a Dark Bay Sire out of a Chestnut Dam) produced his first foal in 2010 out of a grey Hanoverian mare. The foal came out bay with white eye rings, by Inspection time the filly was roan/rose grey in color. I am unsure of what the color would even be called. You can a picture of her here as well as video footage of her and her dam: http://www.pangaeafarm.com/sandrosheirprogeny.html

We were just thrilled the first was not a mutant, good tempered and moved well but received lots of negative comments from superficial people about the coat. It seems dressage people are more tolerant of dapple grey. Anyway, in early March his second foal is due. ALSO out of another grey Oldenburg mare. Should we prepare ourselves for a similar coat color?

Nice filly!
She looks like she's chestnut going grey and totally normal.
She may reach a dapple grey stage at some point on her way to becoming white.
The gray gene turns off the color making cells which is what makes them slowly or quickly turn gray/white.

When you have a gray parent the foal has a 50% chance of being gray.
Sure is a pretty foal! Some people like grays and some dont. I happen to love them!

Ok wait... brought to my attention I need to clarify what I wrote.

IF one parent is heterozygous for the gray gene the foal will have a 50% chance of getting the gene. IF it gets the gene it will show it 100% of the time as gray is dominant.
IF one parent is homozygous, the foal has 100% chance of getting the gray gene and it will show it 100% of the time. :-)
