Drosophila Serrata Genomic SNP Data on Sexual and Natural Selection

Dryad hosts genomic evidence from an evolution experiment on Drosophila serrata. The dataset genotypes over 1,400 single nucleotide polymorphisms (SNPs) across 12 experimentally evolved populations. It was authored by Stephen F. Chenoweth to study the interaction between natural and sexual selection.

Use Cases

• Analyze allele frequency changes for over 1,400 SNPs across 12 populations under different selection regimes.
• Identify the 80 SNPs showing treatment effects to study interactions between natural and sexual selection.
• Investigate genomic regions where sexual selection aligned with or opposed natural selection based on SNP data.
• Correlate SNP allele frequencies with behavioral experiment outcomes on male-induced harm to females.

Strengths

• Genotypes over 1,400 SNPs, providing genome-wide coverage for analysis.
• Data from a controlled factorial experiment manipulating natural and sexual selection across 12 populations.
• Identifies a specific subset of 80 SNPs with measurable treatment effects for focused study.
• Published under a permissive CC0 1.0 license for unrestricted reuse.

Limitations

• The specific number of data rows (e.g., individual fly genotypes) is not provided.
• Limited to a single species (Drosophila serrata) in a novel laboratory environment, reducing generalizability.
• Lacks detailed columnar metadata (e.g., SNP positions, effect sizes) which may require consulting the original publication.
