Re: Re: HYB: ?heredity of orange question(s)

For clarity . . . .there are no orange amoenas, orange with ringed falls, etc...??? They are not simply difficult, but impossible?? 

<<(no dosage effects that result in?
patterns other than self - i.e., orange or not orange?)?>.

Orange is recessive, but it is a combinaion of two recessive genes. It has the tangerine factor, which is recessive plus alternative yellow which is also recessive. So crossing a yellow with tangerine beard X orange will give you lots of orange offspring, probably 100%?
?
The apricot and peach are slightly different genetically.?
?
I would also suspect they have rra 4times. that is recessive reduction of anthocyanin, as org X Org usually gives 100% orange, and none with any anthocyanin. Either that or multiple dosages of "I".?

Orange is full recessive, true? (no dosage effects that result in?
patterns other than self - i.e., orange or not orange?)?
?
Not sure any of you have time/patience to wade thru the following to?
'grade' my logic and results, but sure would appreciate any help available..?
?
15GAK (posted to photos) X AUTUMN RIESLING seedlings are germinating well.?
?
Athough 15GAK looks sort of pale apricot in the photo, I think it's more?
likely yellow with a very pale anthocyanin tint on the standards (i.e.,?
yellow orangish tan). (I forgot to do a hot water extraction to be?
sure). It is I26: white: (white x pink ground variegata or I(s)) X?
GACG-5: pale apricot-orange (what's the difference between apricot and?
orange?);?
?
AUTUMN RIESLING is (Schreiner, R. 2006) Sdlg. KK 1242-A. TB, 40" (102?
cm), ML S. orange apricot (RHS 24C); F. orange apricot (21C), yellow at?
center; beards tangerine. Orange Blossom Special X Status Seeker.?
Schreiner 2006?
?
so this cross should give me probabilities of 1 in 36 having full?
compliment of genes for orange apricot, tho the color may be hidden?
(i.e., recessive white, dominant I(s))??
?
Unless by some chance of luck, 15GAK turns out to be 3/4?
"orange"-pink-yellow, in which case the odds will be 1/6??
?
Some of those, judging from the pale anthocyanin wash on the falls,?
might be apricot ground pastel variegata? Also probability of 1 in 6,?
because, in this case, it's a dominant gene? Or 1 in 2 if it carries?
more than one I(s)??
?
And the presence of blue on the falls of 15GAK tells me that either the?
pollen or pod parent was full recessive white for anthocyanin??
?
plus one of them was at least one I(s)??
?
No wonder most folks make like X like crosses - this gets complicated fast!?
