Genes arising from gene duplication in a given species without any intervening speciation event. Paralogous genes tend to have different functions and contribute to the overall genetic diversity of an organism. However, paralogs can sometimes undergo a phenomenon known as gene conversion, where one paralog's sequence is converted by another, making them identical.
