ᴅᴇɴsᴇ ᴘʜᴇᴏᴍᴇʟᴀɴɪɴ:

(ᴀʙʙʀᴇᴠɪᴀᴛɪᴏɴ: DP) Or, in other words, that elusive and mysterious darkening gene that everyone's always talking about.

"Inheritance studies and cloning have proven that how dark or light a horse’s coat ends up is determined by genetics. This is likely the result of many different genes but in the game it has been simplified to two. Sooty influences eumelanin (black pigment) and pheomelanin (red pigment) while dense pheomelanin only influences pheomelanin (red pigment)." - HAJ Genetics Guide

Statistics:
→ DP is categorized as a common gene in the Roving Gene Sales.
→ It costs $10.00 per strand or 20 GMT tokens in the GMT lab.
→ There is an unknown chance for DP to appear in any create, however the following Rank Special herd helpers guarantee at least one copy of DP:

Cherry Drop (hom DP)
Freaky Friday (hom DP)
King's Ransom (het DP)
Dark Chocolate (het DP)
A Rhythm of Four (het DP)
Hidden Gates - Anniversary Special (het DP)

In an effort to help myself (and others) keep track of what DP looks like on different bases, I've attempted to compile some reference material.
