I'm extremely new to bp genetics, but I am loving the research! So, please pardon any incorrect terms.

Is there a website that explains or lists what morph genes are located in same vs different loci? I hope that question made sense. What I'm looking for is a reference that would tell me if XYX gene would dominate or compete with ABC gene, or if the two (or more) genes would show up together. For example, I found a website that showed Punnet Squares for one set of genes and larger squares for two sets of genes, but they only used Albino and Axanthic for illustrative purposes.

I have read the basic genetics post, as well as many other "genetics 101" articles, so I have a decent grasp on the concepts.
