Can anyone recommend a good reference that discusses how to analyze the 
evolutionary relationships bewteen genes from different organisms?  
Specifically, I need to get correct definitions for homologous, orthologous 
and paralogous genes. I also need to know the correct way to describe a 
situtation in which one organism has a single gene, but a higher organism has 
multiple related genes.  Is it proper to to call the single gene the 
"homologue" of the cluster of related genes? Thank you very much,
