 An example would be a white iris with tangerine beard. So far all tangerine?
plants at least have tangerine in throat part of beard. but petals still have
the plant's tangerine genes, but doesn't show pink (lycopene)


Having genes doesn't mean that trait? is shown.? There may be an upstream
blockage of pigment.? For another example, Laced Cotton.? this is a plicata
genotype, but a white phenotype.

Thanks Chuck.  That's easier to remember!

When you said the trait doesn't necessarily show, did you mean t-factor
isn't necessarily in the part of the beard that shows?

Or did you have something else in mind?  i.e., so much of other pigments
present that it's not apparent without extraction?

Or are there other factors that can suppress t expression completely?

&lt;Should always have tangerine show up in beard, at least in throat.

&lt;Tangerine X Tangerine should all be tangerine. But because genes are there
it doesn't mean trait has to show up.&gt;

Back when I was first tracking pedigrees, I made the mistake of assuming
a description that said orange beard meant t-factor.  Now I assume if it
says tangerine in means t-factor, but I guess this shows that's not
always true either.  Maybe if it says 'red' or 'tomato red', I can
assume &lt;that&gt; means t-factor ;-)
