Axiom™ Trout Genotyping Array (96 format)

Axiom Trout Genotyping Array (96 format) 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
• Comprehensive content: 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 study¹
    - 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)²

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
