In breeding experiments I am aware of, the presence of bright red pigment is
dominant over its absence. In other words (and somewhat simplifying from
the real world), in a cross between a homozygous (both components of the
gene the same) red and a homozygous white plant, the offspring will be in
the ratio of three red to one white.
There are actually numerous genes that modify the flower color in zonals --
hence the incredible variety of shades and tints achievable by careful
hybridizing.

Hi:
I have the first flower on some zonals I grew from my own seed. It came
out bright red. Is this the "default" color genetically?
