The reason that paralogous genes can diverge from each other within the same gene pool, whereas orthologous genes diverge only after gene pools are isolated from each other, is that

#Unit 9. Evolution & Diversity of Life Forms
  1. having multiple copies of genes is essential for the occurrence of sympatric speciation in the wild.
  2. paralogous genes can occur only in diploid species; thus, they are absent from most prokaryotes.
  3. polyploidy is a necessary precondition for the occurrence of sympatric speciation in the wild.
  4. having an extra copy of a gene permits modifications to the copy without loss of the original gene product.
