Effectiveness of SNPs for Sibship Assignment in Farmed Banana Shrimp (Penaeus merguiensis)

Pedigrees are essential components in selective breeding programs to manage genetic diversity and obtain accurate parameter estimates ensure long-term response selection captive populations. High throughput cost-effective sequencing technologies has offered opportunities of using single nucleotide polymorphisms (SNPs) resolve penaeid shrimp pedigrees from mass spawning cohorts communal rearing. Effects SNPs for sibship assignment were investigated on 546 two software programs, Colony Sequoia. Assignment rates accuracies SNP subsets with six different minor allele frequencies (MAFs), four sets SNPs, five genotyping error compared the microsatellite-based pedigree established a previous study. MAFs numbers contributed significant increases accuracies, whereas showed negligible impacts results. Sibship assignments achieved 98% 83%, respectively, minimum number 91 (average MAF ≥ 0.14), exhibited similar resulting patterns subsets. consistencies between SNP-based that could be by thus contribute farmed banana shrimp.
