Supplementary Figure 2: Dot plots of the pseudoautosomal region and the HINTW region.

Dot plots of nucleotide sequence identity in a window size of 50 bp and a step size of 1 bp. (a) Rectangular dot plot showing nucleotide identity between the most distal clones from the short arms of the W and Z chromosomes. The pseudoautosomal region of the Z and W chromosomes begins in telomeric repeats near the TCF4 gene. (b) Triangular dot plot showing nucleotide identity on the W chromosome in the 100 kb adjacent to the HINTW array. Two copies of HINTW are tandemly repeated outside the array.
