I wouldn't bother with "advanced" punnett squares as they take forever to do. Forked Line method only requires you to know your basic punnett square (aka monohybrid) and is far faster to do. It is the method the genetic calc uses. recessive co-dom and dom are just labels we put on how genes express themselves. genes only come in heterozygous and homozygous pairs, they don't care what you label them and all work the same.
For the sake of my typing WT = Wild Trait aka Normal, Het = Heterozygous, Homo = Homozygous
To use the forked line you need to know your basics:
WT x WT = 1/1 WT
Het x WT = 1/2 Het 1/2 WT
Homo x WT = 1/1 Het
Het x Het = 1/4 Homo 1/2 Het 1/4 WT
Homo x Het = 1/2 Homo 1/2 Het
Homo x Homo = 1/1 Homo
from there you basically just multiply each gene probability. without me spending too much time explaining it, check out this video and ask any question you might have.
