Data from: Development and application of an updated haplotype reference panel for association analysis of spontaneous sex reversal in XX rainbow trout

<p dir="ltr">All-female lines are preferred for rainbow trout production because early sexual maturation in males causes reductions in production efficiency and product quality. However, spontaneous males were reported in genetically all-female XX populations. The objective of this study was to identify single nucleotide polymorphisms (SNPs) associated with spontaneous sex reversal to males in XX rainbow trout (sXX sex reversal). Two families, ST15 and ST22, were genotyped with the Axiom 57K SNP array, and 55 significant SNPs associated with sXX sex reversal were identified and 53 out of the 55 SNPs were located on chromosome OmyA26.</p><p dir="ltr">The genotypes of families ST15 and ST22 are included in this dataset. The chromosome numbers and SNPs locations are based on the Arlee reference genome. SNPs cannot be mapped to the genome were assigned to chromosome 34.</p>
