This chip takes advantage of the genomic resources on P. margaritifera that includes genetic diversity markers across Polynesia (N = 44,867), sex markers (N = 884) as well as SNPs associated with color (N = 99) and SNPs associated with genes differentially expressed (DEG) under thermal stress between the Gambier population and Marquises as well as SNPs identified de novo from RNAseq public datasets (N = 23,664). The first validation of the markers and the tools has been to identify putative related individuals and parent-offspring pedigree using multi-parental spawning datasets. This should serve in supporting further genomic selection programs in French Polynesia. Analysis of genotyping results and proposal of SNP marker panels adapted to different populations or uses.
