This is a link to nerd which is one of the few places I have seen discuss double recessives and such. Maybe it will help

Ok, I did that and it worked and told me the results....so How do I make a Punnitt Square for the same thing on my own????
Thanks

this one is correct (only 8 squares required)

normal, pin x normal, pastel, spider, spider pastel...

IM trying to get a bumblebee to a pinstripe, that seems to be leaving quite a bit out...

nope, tis correct
you'll still get your spinnerblast, bee, lemonblast etc...

here's something similar, this is my way, same principle as yours

bumblebee x fire (normal, pastel, spider, spider pastel x normal, fire)

.......N......F
N.....N......F
P.....P......PF (firefly)
S.....S......SF (spire)
SP...SP....SPF (firebee)

Those are all double to double, and i cant figure out how to do a double to a single, you see what Im asking?

So if you want to make a square you have to break down each gene that your trying to mix? Am I getting this?

But how would you figure the odds of normals and co-dom/doms, and the jewels? Isnt there a much bigger square?

ok... look at it this way...
if you breed a pin to a normal, what are the possibilities?
pin and normal (2 different types of offspring), yes?
if you breed a bumblebee to a normal, what are the possibilities?
normal, pastel, spider, bumblebee (4 different types of offspring), yes?
put those 2 breakdowns too the punnett...
2 x 4 = 8 empty squares, which gives what you said in punnett No.2 (below)

___N___ I
NN ______
Np_______
Ns______
sp ________

which results in this...
12.5% WT
12.5% pastel
12.5% spider
12.5% spider, pastel
12.5% pinstrpe
12.5% pinstrpe, pastel
12.5% pinstrpe, spider
12.5% pinstrpe, spider, pastel

So, I was doing it right, just simplified?

in your No.2 example, yes...
your No.1 and 3 are wrong
