An efficient way is to understand what classification the morphs are:

spider=dominant

pastel, cinnamon, yellowbelly,....etc.=co-dominant

albino, pied, clown...etc...=recessive

Then you can understand all the pairings in terms of

(homozygous) recessive x dominant = 50% dominant het for recessive, 50% recessive etc...

Is there anything in particular you're having trouble with?
