Hello Folks,

If a novice can get simplistic here, would I be able to apply via a chart,
say back
to the great-grandparents, by plugging in the apparent expression of the
pigments
and note the possible pigments perhaps unexpressed and use it to determine
at least some of could be expected, or predicted, using the end result as a
parent? Obviously with another matching chart for the other proposed
parent. And is it feasible to extend these to patterns, heights (say if a
grandparent TB X dwarf species) and track what appears to been expressed
down through several generations? Can one extrapolate by such Checklist
digging traits that appear more or less dominant and those that are only
likely to appear when both parents exhibit the trait or can be determined to
have likely inherited it and are merely carriers?
Lots of Checklist reading here, I think. With even more digging, could you
check listings for progeny of the cultivars proposed as parents and further
check progeny of parents, grandparents etc and perhaps determine that
some traits are not likely to carried at all and thus narrow what might be
expected even further.
