Up until this Spring there had been no "extreme-stripes" produced from non-related breedings and although numbers were not completely supporting it I thought last year that the extreme-stripes might be "super" of a codom' trait.(One of the '09 poss het T-snow was a "chainlink patterned, but born dead; I had thought largely the effect of the "Aztec-like het pattern" combined with the heavy circle-backing of the sire.) Since I was getting both the very light "T-positive mimics" with and without extremestriping, I had thought it possibly a super or homozygous recessive probably separate from the stripe gene. Numbers of the "T-positive mimics" also did not conclusively support being a "super" or homozygous recessive. I got a very, very nice example of extreme-stripe from breeding to a totally unrelated non-striped snake in my first litter this Spring proving it to be simple dominant, and just one of many possible expressions of the Mayan gene. So, going back to my original belief of what a Mayan is, the numbers pretty much add up that the "T+ mimics" are all the hypomel-like and hypomel/hypoerythristic (what I call "smoke"
that are also true hypomelanistics. The Mayan is a "jungle-type" gene (not to be confused with the Swedish line jungles) in that it produces both color and pattern variances, some of which are more extreme than Swedish jungles...especially colors. Markers are similar to jungles (light eyes often with red, orange or amber tint, broken head spear, pattern aberrancies, line of purplish speckles on sides, holes/bubbles in pattern, etc.) I do not believe there is a visible "super," and thus there MAY also not be the genetic problems/sterility associated with super jungles. Color variations range from slightly hypermelanistic to hypomelanistic (even to the point of having a complete pattern wherein the black is visibly non-existent; appears to exist as precursors to black much like T-positive albinos), and from high red/orange/yellow to hypoerythristic (even to the point of being virtually a visible "ghost" with slight pale pinks/yellows), and every possible combination in between! Pattern can be visibly normal, jungle-like zig-zagging, extreme dorsal striping, reverse striping, Aztec-like blocky patterns, circle-backing, ladder-tailing, or any combination! From the few litters I've produced it seems that the more striping an individual has the more likely it will throw better and more stripes in litters it produces; same with the extremely light color/"smokes." Some of mine do have some Hog Island in the ancestry, but some do not....locales involved influence color to a degree (those with 1/4th Hog ancestry are brighter colored than those with 1/8th), but have no effect on the striping and pigment reduction. That is: You get Mayans no matter what you breed to the original Mayan Nicaraguans. So, it is NOT just because there's some Hog Island in them; if so, the sunset/het sunset producers would be over-run with them! Because of the extreme reduction of reds in some individuals I think it's going to be very interesting when bred to bloods, super Marrons, etc. Since the "T-positive mimics" do not dull out and darken hardly at all as they age, it is thought that it will eliminate this trait
(the "leaky gene"
in morphs such as VPI and BW Caramels, so that they retain the beatiful juvenile colors! Because of all the variety of colors and patterns involved it has taken time to get this far with the genetics. It would have been easy to fixate on one particular color or pattern and work to prove that alone as codom or recessive, while ignoring the "low-expression" examples that did not fit with my expectations. You are free to disbelieve what I'm telling you, and insist this is no morph, but it will not change the facts
I wish everyone working on proving out genetics of their possible new morphs luck in their endeavors, and encourage them to continue despite the onslaught of negativity that seems to surround anything new coming to market in the boa world.
These are 1/8th Hog Island percentage (from breeding het sunset cross Mayan Nic to El Salvador het pewter):



These have no Hog Island (from breeding Mayan Nic to Nic X Cancun het T-positive Snow):
