Keith-

i agree with your point that variation does not have to be a mutation- could be selection, who knows but I agree with Brandon, with the proven extreme lavender albino lines when crossed to an axanthic/anerythristic, the hets do show red but the double homozygous phenotype (snow) doesn't show red at any stage as much as we have seen to this point. it has been a (fun but) futile argument up to this point because now people have done the breeding with a proven red line. I think there is some substance to the argument there is some effect on the genes controlling red pigment.

From some of the other forums (bull/pine discussing red bull genetics) it doesn't appear that red or lack of it- at least in those species - is simple recessive. I think some with the most experience say it is co dominant, so this may not be a simple point to prove out.

I think if you look back to my new year's post, one of my resolutions was to keep this axanthic/anery argument going!

have a good day,
