A neglecta is an amoena with one dosage of Anthocyanin enhancement.
Two Is have a white area around beard. Three and four go to rims, but different amounts of rim..
Of course ther are interactions with Ae (anthocyanin enhancement) genes.
If four Is than you won't get any solid anthocyanin flowers. Half will have no anthocyanin if HOM has one dosage of I. More will be solid cartenoid if more IS in HoM.

I had to go hunt up a picture of JB, not blooming this year, & I was
mis-remembering it as having an anthocyanin band with an orange band at
the rim. Not so!
Let's see if I can remember what you and Neil tried to teach me over the
years - one dose of I(s) is amoena, two is neglecta, three is the outer
band (like JB) and nobody knows what four is. Or maybe it's no anthocyanin.
Pretty sure HOM doesn't have any I(s). But most of my crosses with it
have been with pinks & oranges (i.e., greenish, yellow or white
seedlings), so I don't know.
<Assuming HOM doesn't have I(s).>
HoM is definitely at least t, possibly tt. 3 or 4 out of what seems
like a zillion seedlings have had t beards, soaked to check. If I count
up how many actual seedlings I've bloomed from HoM x pink, I guess that
would tell me. 1/64 = 2t? I think that's probably close to what I've
seen. No pinks so far, just mid or dark yellows with t beard.
<And a few solid yellows (assuming no t, tt or ttt in HOM, in which case
some plants with orange ground or solid orange plants.>
So I'll pretend that one or more of the remaining handful of seedlings
from the cross will (a) live, (b) bloom eventually, and (c) will be
orange (which was the plan, tho a banded orange like JB would be nice too!).
