The "n's" are confusing and not helping. Lets try it a little differently.
P = wild type (wt) pastel gene - snake will look normal
p = mutant pastel gene - snake will be a pastel
So PP = normal snake. Pp = pastel. pp = super pastel
Same thing with spider:
S = wt
s = spider
So SS = normal. Ss = spider. ss = homozygous spider (not sure if its been proven if these exist or if they're lethal?)
So a bumble bee would be: PpSs. From there you can plug it into your punett square:
.......PS.....pS.....Ps......ps
PS PPSS PpSS PPSs PpSs
pS PpSS ppSS PpSs ppSs
Ps PPSs PpSs PPss Ppss
ps PpSs ppSs Ppss ppss
So you can go through and work out the phenotypes on your own. But labeling the pastel and spider genes with "n" is confusing, because how to you delineate between whether the '"n" is referring to the pastel or spider gene? Generally most use a capital letter for the wt allele, and a lower case for the mutant allele. It makes working them out easier doing it that way.
Hope this helps.
