Axiom Trout Genotyping Array was designed under the Affymetrix Expert Design Program in collaboration with the National Center for Cool and Cold Water Aquaculture, USDA-ARS, USA, and AquaGen, Trondheim, Norway. The array includes 57,501 markers and is available in both 96 format and 384 format.

Axiom Trout Genotyping Array offers a standard high-throughput, cost-effective, and robust genotyping technology to conduct genome-wide association studies (GWAS), to study genetic architecture, perform marker-trait association, and to increase accuracy of breeding programs. The high marker density on the array ensures a broad coverage of the trout genome to provide representation of all regions in the genome.

Features of Axiom Trout Genotyping Array

• The array includes 57,501 markers spaced across the genome as follows:
  • 17,000 markers that are unique to SNPs discovered in a previous USDA study
  • 20,000 markers unique to an outbred Norwegian commercial population
  • Amino acid shifting SNPs
  • SNPs preferentially located within a gene and with minor allele frequency (MAF) >0.2
  • Y chromosome-specific SNPs near the sdY gene (male-specific in rainbow trout)

Applications of Axiom Trout Genotyping Array

• Complex trait research and molecular breeding
  • GWAS and quantitative trait locus (QTL) mapping
  • Identification of economically important traits
  • Improved accuracy in aquaculture breeding programs through genomic selection

• Population and evolutionary genetics
  • Development of new breeding populations
  • Differentiation between fish of different origins
  • Gender determination via sdY chromosome-specific probes
  • Differentiation of farmed and wild populations

Array format: 96-array and 384-array plate
