Gene traffic mediated by transposable elements shaped the dynamic evolution of ancient sex chromosomes of varanid lizard Open
Lizards exhibit rapid turnovers and a much greater diversity of sex determination mechanisms compared to birds and eutherians. This makes the conserved ZW sex chromosomes of anguimorph lizards originated over 115 million years ago a seemin…

The role of unbalanced segmental duplication in sex chromosome evolution in Australian ridge-tailed goannas Open
Varanids are known for conserved sex chromosomes, but there are differences in the size of the W chromosome but not in morphology among species representing varying stages of sex chromosome evolution. We tested for homology of the ZW sex c…

Varanids are known for conserved sex chromosomes, but there are differences in the size of the W chromosome among species representing varying stages of sex chromosome evolution. We tested for homology of the ZW sex chromosome system with …

Fixed Allele Differences Associated With the Centromere Reveal Chromosome Morphology and Rearrangements in a Reptile (<i>Varanus acanthurus</i> BOULENGER) Open
Chromosome rearrangements are often implicated with genomic divergence and are proposed to be associated with species evolution. Rearrangements alter the genomic structure and interfere with homologous recombination by isolating a portion …

Unbalanced segmental duplication of W chromosomes in Australian Ridge-tailed goannas Open
Sex chromosomes are mostly conserved, but in some cases are variable within species. Varanids are known for conserved sex chromosomes, but there are differences in the size of the W chromosome among species representing varying stages of s…

Extreme genetic divergence indicated by chromosome rearrangements Open
Chromosomal rearrangements are often associated with local adaptation and speciation because they suppress recombination, and as a result, rearrangements have been implicated in disrupting geneflow. Although there is strong evidence to sug…

Diversity of reptile sex chromosome evolution revealed by cytogenetic and linked-read sequencing Open
Reptile sex determination is attracting much attention because the great diversity of sex-determination and dosage compensation mechanisms permits us to approach fundamental questions about mechanisms of sex chromosome turnover. Recent stu…
