New Blue Project....

[Dragoner]

I’m not sure I read you right… and ultimately I’m just theorizing… But…

I do believe it is possible for one fish to have the mutation for blue as well as the mutation for gold (Leucism) simultaneously…

But I believe that the gene (allele) which cause the blue will be “overridden” by the gene (allele) that causes gold (Leucism)… since the nature of Leucism is to “turn off” color produced by pigmentation…

So these traits are Mendelian?

So these traits are Mendelian?

Yes...

and I understand that two separate mutations can express themselves in the same specimen through this process...

But since these are both tied to color producing pigment (color producing cells), they have the potential to have a direct impact on each other...

I believe if one specimen were both "blue" and "gold", the "blue" would tell the color producing cells to make blue color... but then the "gold" (leucism) would fail to supply the cells with the proper proteins to make color at all... Thus resulting an a specimen that has the mutation for both “blue” and “gold“… but only expresses the “gold“…

I know I’ve been repeating myself a bit… But I figure the more ways I present it the more people will be able to understand my thinking… Also keep in mind I confess this is only my hypothesis. I do not claim to have this whole thing “figured out” and I welcome anyone else to present similar or opposing hypothesis. I may ‘debate’ them, but only as someone interested on the topic and interested in deepening their understanding, not as someone “out to prove you wrong”…
