It also might be noted, especially in the various
posts Chuck Chapman has made about plicata alleles and how they interact to
produce the various types of known plicata patterns do not include veined forms
that are from purely plicata ancestry.
Those that show butterfly-wing or radiating
patterns out from the beard have no explanantion from the four known pl
alleles-- PL, the non-plicata "normal" genetic condition in solid color forms,
pl in the plicats with stitching or dotting or both in the borders of the
petals, and often in a streak down the center of the fall, pl-a, the glaciata no
anthocyanin form, and pl-u (sometimes referred to as pl-lu), the one responsible
for luminata.
None of these in combinations produce the kind of
veining in the Thornbird seedling we've been discussing. The veined
patterns occur, either by pl alleles interacting with other genetic components
not at the plicata locus, or are the result of variations on something else
entirely--probably the Umbrata-spot group in the forms noted in the varied
species *variegata* clones.
