Introgression Test Details for Mimetic Lepidoptera Across 120 Million Years

46.6 KB of genetic association data for convergent color pattern evolution in mimetic butterflies and moths. The dataset, authored by Yacine Ben Chehida and last updated on April 30, 2026, likely contains details on introgression tests and genetic variants associated with wing color patterns across lineages that diverged up to 120 million years ago.

Use Cases

• Testing hypotheses about genetic introgression and allele sharing based on the study's findings on hybridization.
• Analyzing the association of noncoding regulatory regions near specific genes (ivory, optix) with phenotypic convergence.
• Comparing supergene architecture, such as large inversions containing the ivory gene, across distantly related mimetic species.
• Investigating the predictability and constraints of evolution by examining repeated parallel evolution of regulatory switches.

Strengths

• Data covers a wide evolutionary timescale, with lineages diverging between approximately 1 and 120 million years ago.
• Includes genetic details from multiple neotropical lepidopteran lineages, including seven Ithomiini species, Heliconius butterflies, and a Chetone moth.
• Released under a permissive CC-BY-4.0 license, facilitating reuse and sharing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale statistical analyses.
• The 46.6 KB file size indicates a very limited scope, likely containing summary or test details rather than raw genomic data.
