Centromere evolution and CpG methylation during vertebrate speciation.

Comparison of centromere sequences between interfertile medaka strains that separated 18~25 My ago. Also, within a species, homologous pairs of centromeres (derived from the same ancestral pre-teleost (350 My ago) chromosome) were conserved, and acrocentric ones were shown to evolve slower.
