Information of 80,123 SNPs included in the Macrobrachium rosenbergii 80K liquid chip

1. Dataset OverviewThis dataset provides comprehensive information for 80,123 high-quality single nucleotide polymorphism (SNP) markers from a custom 80K liquid chip, developed specifically for Macrobrachium rosenbergii—a commercially important freshwater prawn species. It serves as a foundational resource for aquatic molecular breeding, crustacean genomic research, and quantitative trait analysis, adhering to FAIR data principles (Findable, Accessible, Interoperable, Reusable).2. Data Details2.1 Format & StructureFile Type: Microsoft Excel (.xlsx)Dimensions: 80,124 rows (1 header row + 80,123 SNP entries) + 8 columnsKey Column Descriptions:SNP ID: Unique identifier (format: "Chr[Chromosome Number]_[Physical Position]"; e.g., "Chr6_24000952")Chromosome: Chromosomal location (e.g., "Chr1", "Chr21")Position: Physical position on the chromosome (base pairs, bp)Structure Type: Genomic region (8 categories: UTR3, UTR5, exonic, intronic, intergenic, upstream, downstream, upstream;downstream)Ref/Alt: Reference and alternative nucleotides (Ref: A/C/G/T; Alt: single-base substitutions + small indels)Function Type: "functional site" or "background sites"Associated Trait: Linked economic traits (e.g., "Abdomen weight of adult prawn", "Cumulative survival time at low temperature")3. Data Quality & ValidationCompleteness: >99.9% of entries have non-missing values for key fields (SNP ID, Chromosome, Position, Function Type)Uniqueness: No duplicate SNP IDs (verified via duplicate detection)Quality Control: SNPs filtered for call rate >99% and minor allele frequency (MAF) >0.05 to ensure reliability4. Usage4.1 Intended ApplicationsGenetic map construction and quantitative trait locus (QTL) mappingGenomic selection for growth and low-temperature resistance in M. rosenbergii breedingPopulation genetic analysis of wild/cultured prawn stocks
