Sunset/Sunrise
Through my test breedings I have found the tangerine in Sunsets/Sunrises to act polygenic. I haven't seen a recessive component to the morph besides the blizzard.
I have included this quote below from the founder Nick Stark for the history of the line...
"My original hypothesis was that if I bred a Tangelo to a Midnight Blizzard and then bred their offspring together I could get the orange of the Tangelo to fill in where the dark pigment was in the Midnight Blizzard. While they haven�t turned out orange it appears as though the results are close to what I had set out to do. I will give breeding history chronologically, hopefully that makes it easier to follow.
2006 I bought a male Tangelo from Ron Tremper.
2007 I bred the Tangelo to a group of Midnight Blizzards(4) all of the offspring expressed the �normal� phenotype.
2008 I bred F1 x F1 offspring from the above group; it produced a very wide range of offspring, normal, Blizzard, Blazing Blizzard, Tangerine, Tangelo, and the first male Sunset. Keep in mind that out of 180 offspring produced by the two F1 groups I only produced the 1 male Sunset.
2009 I had hoped to breed the male Sunset back to the F1 females that however did not happen; instead as soon as I introduced a female to him he everted his hemipenes. This would come to be how he responded to every female and it was clear quite quickly that he was not going to breed. Without the Sunset I had to repeat the breeding from the year before and do F1 x F1. This time around the results were similar but I produced two females, one Sunrise and one Sunset, but no males.
2010 I bred one of the F1 males to the two females produced the year before. In this breeding my odds got much better (two out of twenty nine), I produced a male Sunrise and one more female Sunset.
2011 This year I bred the male Sunrise to the female Sunsets and the one Sunrise I had produced. Because the male and females in 2010 were late hatchlings they didn�t start breeding until later this season but we produced all Sunsets or Sunrises from this group, a mix of sixteen Sunrises and Sunsets. This coming year we have a small group of Sunrises and a small group of Sunsets that we will be breeding. At this time we do have a few surplus males that we will be releasing (incubated to be female but turned out to be male.) "
