Mike has provided an excellent synopsis. If you want more details, read
on. Otherwise hit "DELETE"....
Dr. Peter Werckmeister described this as a two-stage process. =
Concentrations of malvidin APPROACH red in appearance and if the blue ton=
es
of delphinidin can be eliminated the result is a redder red. This is
similar to approaching pink through the pale red-violet anthocyanidins --=
some are quite pinkish, but none are the clear flamingo pink of lycopene.=
=
It's different because the pink and pinkish pigments are chemically quite=
disparate while the reddish and red pigments are quite similar.
The pigment that produces scarlet (in roses, for example) is pelargonidin=
=2E =
So far, it has not been detected in iris, but the logical progression of
mutation is from malvidin to pelagonidin (the chemistry and genetics are
definitely beyond the scope of this discussion). Werckmeister theorized
that inbreeding malvidin-carriers could not only lead to redder flowers b=
ut
would also increase the chances of obtaining and detecting mutations that=
produce true red pigments.
