Splits Tree reticulated network of all alleles encoded by the preproalvinellacin multigenic family in A. pompejana: (A) the NeigborNet network together with (B) the schematic reconstruction of natural intergenic recombinants using the NJ tree topology obtained with the MEGA 5 software and the HKY model of substitutions. Sequences from the 5′ region were used in the two reconstruction methods and the six paralogs (Parx) as well as their intergenic recombinants (Rx) are represented by boxes in which the red, dark green, light green, blue, yellow and purple colors represent the genetic paralogous background and their proportions in recombinants, darker colors, the portions of the recombining alleles which accumulated their own set of mutations, and bars correspond to indel polymorphisms (including alleles with the 34 codons deletion in Par5).
