Fig. 2.

Inverted duplications flanking the FLNA–EMD chromosomal segment in eutherians. The positions and orientations of genes (arrows) and duplicated segments (filled boxes) are illustrated for each species. Species-specific refers to a sequence duplicated in a single species, ordinal refers to a sequence duplicated in more than one species from the same order, and superordinal refers to a sequence duplicated in at least two species from two distinct orders. The position of sequencing gaps within the duplications is indicated by *. The intraspecies divergence between duplications as measured by the number of substitutions per site was calculated by using the Kimura two-parameter (K2P) model (50) and is shown on the right along with the standard error.
