Polymorphic sites and indels in the Amel-X and Amel-Y regions in the Cetacean species studied. (a) Nucleotide positions are represented above and on the left side the names of the haplotypes. All positions are represented on the first sequence and each matching nucleotide on the other haplotypes is represented by a dot. (b) Indels are numbered (first row) following their order on the aligned sequences. They are characterized by their position (second row) and their length (third row). In both tables, shaded areas corresponds to the region holding the large insertion.
