In a worm genome, the gene meg-1 is adjacent to the gene meg-2, and they are transcribed from the same template strand. These two genes encode proteins with largely identical amino acid sequences, although meg-1 has additional sequences not found in meg-2. The most likely explanation for how these two genes evolved is
