Forkline can do anything a Punnett square can do only faster. And if you only want the probability of one particular outcome and don't particularly care about the rest, forkline can give it to you without making you figure out all the possible results of a mating. The Punnett square cannot do this.

Example: What is the expected fraction of moonglow babies from a salmon het Kahl albino het anerythristic x Kahl albino het anerythristic mating?

Salmon x normal -->
1/2 salmon
1/2 normal

het Kahl albino x Kahl albino -->
1/2 Kahl albino
1/2 het Kahl albino

het anerythristic x het anerythristic -->
3/4 normal looking (66% probability het anerythristic)
1/4 anerythristic

Moonglow is salmon, Kahl albino, anerythristic.
1/2 - 1/2 - 1/4 = 1/16 moonglow.
