OB are still jut a different line of YB regardless.Originally Posted by AGoldReptiles
Goblins( RDR) and Bling YB ( NERD) are just lines of YB. They don't do anything different than any other YB. Orangebellies have the potential to make something different. Ultras and Graphites, that to me makes them different. Let's use the Ultra as an example. They have a lot if purples and color that fades to the typical Ivory color as they age as stated above. What is going to happen when other genes are in that animal? Will a Pastel Ultra keep it's color better? I think the OB has a lot to be seen yet.
I don't see how it is possible for the Ultras and Graphites to be a recessive trait. OB x YB can make Graphites, so unless that YB happened to be a (Het.) I just don't see it being plausible. Hopefully someday it will all be sorted out.
I have been working with OB's for a few years now. I don't have any YB animals to make any comparisons as for dark, light, orange, or yellow, but I can say that the OB morph is variable just like any other morph. I have produced dark ones, bright ones, ones with more orange and ones with more yellow.
At the time I talked to Ben (who started the project) his theory on the additional gene was that it was a recessive gene attached to the OB, the Ultra in his opinion at the time was and Ivory carrying that specific gene. In other words his thought at the time that
OB Het? X OB Het? = Make graphite and ultras (ultras being ivory het?), at the time more breeding needed to be done to confirmed this and I am not sure where he stands now.
As for OB X YB producing Graphite does not prove it's not recessive the YB could have very well carry the gene as well.
Just like not all OB to OB pairing make Ultras or Graphite hence the additional gene.
