RADseq Data from Australian Cricket Species for Sex Chromosome Analysis

RADseq data from a 16-population transect of two closely-related Australian cricket species, Teleogryllus commodus and T. oceanicus. The dataset was generated by Peter A. Moran to study opposing patterns of intraspecific and interspecific differentiation in sex chromosomes and autosomes, published in 2020.

Use Cases

• Compare genetic differentiation on putative X-linked loci versus autosomal loci between Teleogryllus commodus and T. oceanicus.
• Analyze population differentiation within each species using X-linked and autosomal markers from the 16-population transect.
• Investigate relative X-to-autosomal genetic diversity patterns to test for deviations from neutral expectations.
• Examine genomic signatures of recent population expansions in both cricket species using the RADseq data.

Strengths

• Data covers 16 distinct populations across two species, providing a transect spanning allopatry and sympatry.
• Focuses on a classic study system for sexual selection with a rare exception to Haldane's rule (sterile hybrid females).
• Dataset is published under a CC0 1.0 public domain license, allowing unrestricted reuse.

Limitations

• Sample size and specific row/column counts are not provided, limiting precise assessment of statistical power.
• The dataset is specific to two Australian cricket species, which may limit generalizability to other taxonomic groups.
• Data collection method (RADseq) may have inherent limitations in genome coverage compared to whole-genome sequencing.
