Just one correction: orthologous and paralogous are not genes that are distinguished by being in the same location or not. They refer to the ultimate event that lead to the separation as two different genes, in the case of orthology refers to a speciation event and in the case of paralogous genes, to a duplication event. The terms are in my oppinion not great and I wish they would mostly disappear from scientific discussions.
