Pacific Lamprey Genotypes and Phenotypes Across Species Range

Genomic data from 518 Pacific lamprey individuals across the species range, genotyped at 7,716 SNP loci, forms the core of this dataset. It was produced by Jon E. Hess of the Columbia River Inter-Tribal Fish Commission to study trait variation. The dataset includes genotype-phenotype associations for traits like adult body size, sexual maturity, and migration distance derived from a subset of 302 SNPs in 2,145 individuals.

Use Cases

• Identifying genomic regions associated with body size based on SNPs on chromosomes 02 and 04.
• Investigating genetic markers for female sexual maturity using SNPs on chromosome 01.
• Modeling spatiotemporal distribution of phenotypic traits like size and maturity across a geographic range.
• Informing species restoration and management strategies by linking genotype to fitness-related traits.

Strengths

• Dataset includes genotypes from 7,716 SNP loci across 518 individuals, providing a substantial genetic baseline.
• Phenotype associations are tested on a large sample of 2,145 individuals for multiple traits.
• Geographic coverage spans the species range, supporting population-level analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the primary genotype or phenotype tables is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
