@Duvelina All my sims get traits that I am happy to play. This is a genetics save and traits are only important insofar as I have to be able to enjoy playing the sims while they have children. From memory, Lou's dominant trait is virtuoso and Joe's is artistic. I can't for the life of me remember what Leo's dominant trait is.
As for Lou and Joe looking like twins, I can see what you mean although they are different. Because of the genetics mod I am using, sims are not inheriting whole features from their parents like they would with EA genetics. There are subtle differences if you look closely. For example Leo's eyes are closer and his nose is shorter and narrower.
