The axanthics you are reffering to are allelic. In other words the genes are related except for rthe BHB axanthic which I call an anerythristic florida king.
The look of the axanthics depends on the line it came from. If you have nice phenotype parents than you will get nice axanthics.
NE = very light adults with almost no distint pattern
Lemke and outcrossed lines= very dark with heavy pattern adults
The neonates of the NE are not very good looking when compared to the Lemke line. The Lemke line usually produces nice "blue" babies. The NE does not. But when they grow up there is a huge difference with the outcrossed Lemke lines retaining a pattern and the NE line becoming increasingly speckled.
I have sold pure New England line axanthics for many years and all the babys turned out very speckled with a disperesed patern. I have never hasd a dud turn out from the NE line that was kept pure. I did some experimantation a few years back and wanted to see if the Lemke and NE lines were allelic. The Lemke line seems darker because the pattern is more distinct, causing a darker appearance. One time I did cross the Lemke line with the NE line and they turned out more like the darker Lemke line. They werre okay but nothing close to the pure NE's. There are people out there selling NE's that have been crossed out with the Lemke line and are marketing them as pure NE's even though they came from me.
Also there are a lot of outcrossed Lemke axanthics out in the market. Most have been out cossed to different lines and what I have seen are sub par axanthics. Most are priced accordingly. I see axanthics going for $25. on breeders tables at the Daytona Expo every year. I have seen than as low as $20. the l;ast 2 expos. But those are a far cry from what attracted people to axanthic SOUTH FLORIDA "brooksi" in the first place. These usaully come from Florida breeders who have outcrossed them to what they found in their backyards. These are florida kings and not the south florida brooksi that these lines originated from.
It seems natural evolution that Florida will do this. They have been doing backcrossing with the albino calif king to florida kings for many years. Bottom line is what you get are not very nice looking axanthics and definetly not a line from the original nice s. florida phenotypes that these resulted from. Then you will also see unscupulous breeders selling New Englands line brooksi that are not NE's at all. Delving further discussion with them usually reveals they don't know what they are talking about and end up saying they bought the babies as a group ( from another broker or unkown breeder) as NE's. Ha! Any breeder that has pure NE's would not be selling them to a brooker.
