Someone understands?

India blue Pied X Black Shoulder ..... BBTP X bb why not BBTP X BBbb ... ?

India blue Pied = TB BP = 1 gene white ( T ) + 1 gene pied ( P ) + 2 genes blue ( B ) .... OK !

Black Shoulder = 2 X Ib ..... NO colour ? or here I is the blue gene ?

There is a gene BLUE of Blue PATTERN ( I ) and a gene BLUE of Blue COLOR ( B ) !
I = Male IB wild barring pattern ?

Then, we are going to mate brother and sister
The genetic profile of a bird has 4 letters ... why here 8 letters?

India blue Pied X Black Shoulder ..... BBTP X bb why not BBTP X BBbb ... ? Actually using his terminology it should have been BBTP x bbII. I is the marker for the location having neither the T or P marker.

India blue Pied = TB BP = 1 gene white ( T ) + 1 gene pied ( P ) + 2 genes blue ( B ) .... OK ! To clarify, B only represents the wing barring gene, not the color blue

Black Shoulder = 2 X Ib ..... NO colour ? or here I is the blue gene ? The color blue as opposed to any other color is not addressed in his charts. His language is BAD on this point. I is the lack of T or P at that position and B and b represent wing pattern only.

See my comments above. His charts are good but his use of the color blue is not correct. He is only addressing two gene pairs/locations. One is the pair that can be I (no white or pied marker, T (white) or P (pied). The other is the wing pattern only as either B (barred) or b (blackshoulder).
 
Thanks for the answer !
When he mate brother and sister :
He mix the genes than he got 8 lettres.PB Pb IB Ib why ?

A new things .... for him the PP = dark pied has no white feathers in the wings ( or PPBB and PPBb ) ! only the split white has that .
And other things interesting : TIbb is a black shoulder with white feathers in the wings .

He said:
"TIBb=1 white gene(T), 1 blue pattern gene (I), 1blue color gene (B) and one b.s. gene (b)"
So as you said, I and B are talking about pattern !
I is lake of P ( Pied ) or T ( White ) ?? other pattern are Barred and Black shouldered.

When you use a prunett square you have to have a separate column or row for each possible combination of genes you are considering. So there are two wing pattern possible combinations for each of the two pied/white/normal combinations. For every gene pair under consideration the number of columns/rows in crease by a factor of two.

Not sure I totally agree with his marking notes. Split pied usually shows no white in the wings or throat but dark pied does.

He said:
"TIBb=1 white gene(T), 1 blue pattern gene (I), 1blue color gene (B) and one b.s. gene (b)"

Yes. I like to use "location" as the position of the genes instead of lake. I represents an empty location.
See above.
