Nevertheless, numerous insertions from multiple LINE-L2 clades were found, suggesting ongoing transposition with potential contribution to speciation. Contrary to expectations the afgp locus was highly similar between haplotypes, except for large length allelic variants of afgp genes. Analysis suggests a model for the afgp locus expansion in H. antarcticus through segmental tandem duplications involving two pairs of afgp genes at time.
