F4 Test Results for Introgression in Mimetic Lepidoptera Lineages

Yacine Ben Chehida's dataset contains results from f4 tests of introgression, investigating genetic mechanisms of convergent color pattern evolution across multiple mimetic neotropical butterfly and moth lineages. The dataset, last updated on 2026-04-30, is shared under a CC-BY-4.0 license. It is a small, 36.2 KB XLSX file.

Use Cases

• Analyzing genetic association with convergent color pattern switches based on noncoding regions near the genes ivory and optix.
• Investigating the role of a ~1 Mb inversion containing ivory in color pattern variation in a day-flying moth species.
• Testing hypotheses about allele sharing via hybridization in closely related Ithomiini butterfly species.
• Assessing the predictability and constraints of evolution across large (~1 to 120 Mya) evolutionary timescales.

Strengths

• Focuses on a specific, well-defined evolutionary question regarding convergent evolution across multiple lineages.
• Includes data from diverse taxa: seven Ithomiini species, Heliconius butterflies, and a Chetone moth.
• Covers a wide evolutionary divergence range, with lineages separated by up to approximately 120 million years.

Limitations

• Row count is unknown, which may limit suitability assessment for statistical analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (36.2 KB), indicating limited scope and likely a summary or focused subset of results.
