The Phantom Gene

Phantom Genetics
Phantom is a recessive gene, and one of the very first genetic mutations I stumbled upon in my collection - this is not to say it was rare or exclusive, just that I was first to observe and identify it. I also named it - twice. More on that later. :-)
So I bred two full pinstripes together and got a pinstripe hatchling that lacked most, but not all of the dorsal markings. It had the pinstripe structure, but no dorsal markings. The laterals were also faintly visible, but undeniably there. It didn't take long for me to understand this was a recessive mutation, as I was heavily into breeding python morphs at the time.
The Phantom Name
This is probably the first time I tried to name a crested gecko morph and it was a less than rewarding experience. I started posting photos of Phantoms and calling these geckos my "Patternless Pinstripes". The small, but vocal crested gecko community of the mid-2000's were divided - some liked it, but a lot said it made no sense because they weren't really patternless. So I went back to the drawing board and came back to them with Phantom, which was universally accepted immediately. Thankfully they fell in love with the term Phantom just as fast as they had decided they hated Patternless Pinstripe. :-)
The ACR Phantom Collection
After I had discovered how the Phantom gene worked, I worked with it very sparingly for probably the next 10+ years. I wanted my Dalmatians to all be Phantoms with good Pinstripe structure, so I just ran with that. Up until 2016-2017, I thought putting white on a Phantom was a lost cause - but I can't say I really tried until I got the idea to introduce white to my red and black spotted Super Dalmatians. I started trying to add Whiteout (Whitewalls) to those and a whole new world was opened up to me. As it turns out, you can absolutely add white to Phantoms and there are multiple other cool genes and traits we're beginning to tinker with as well. The other thing I like is that we can still use genes like Margin and Empty Back to play with the dorsal of Phantoms because they're still affected.
I tinkered for a few years until 2019, which is when I finally decided that I wanted to build an entire Phantom colony to parallel my non-Phantom collection, boldly stating that we'd be producing as many Phantoms as non-Phantoms by the time I was done. It's now 2025 and if we're not already there, we're close - and more than half my keepers are currently Phantom combos. As much as I love a good dorsal pattern, I really like the idea of having a Phantoms as a "clean slate" version to do things with the laterals, structure, color, you name it.
