Tested Pony: Millennium Midnight

Millennium Midnight, better known as Oreo, was born in 2000. She was born on the Leonard farm but went through the auction that year. Her sire was the bay tobiano Miracle Man. The dam listed on her papers from the old Chincoteague Pony Association was Chantilly Lace. However, that's either not her dam or Chantilly Lace isn't who we thought she was. More on this later. Oreo spent most of her life as a broodmare and spent many summers at the Chincoteague Pony Centre. Here's a video I took in 2010 at the Centre: https://youtu.be/HZ2H8klfrv0 From 2018 to 2020 she lived on Assateague having been loaned to the Chincoteague Volunteer Fire Company. Here's another video of her from this July in her retirement: https://youtu.be/Nv7ykK5u6J0

Oreo is a bay like her sire. Her test revealed she has two copies of black and agouti. This means her foals could only be bay and indeed they all were. Back to the question about her dam, the mare everyone thinks was Chantilly Lace was a chestnut. A chestnut can have a copy of agouti but can't have a copy of black. So that mare can't be Oreo's dam, since she has two copies of black and had to have inherited a copy from each parent.
Her white stripe "cream in the middle" gave Oreo her nickname. That white came from tobiano pinto of which she has one copy. She had a solid colored foal so it wasn't a surprise at her test result showing one copy.

Oreo doesn't have a dorsal stripe but she has one copy of non-dun1, aka nd1, which can cause ponies to have primitive markings like dorsal stripes.

She has one copy of Eden White 3, one of the more recently discovered white patterns. This is probably why she has a star and a snip. Still finding out what all EDXW3 can do. I don't know which parent EDXW3 came from but I've been eyeballing Miracle Man for forever at possibly having had something other than just tobiano. Perhaps this was it!
