The number of polymorphic and monomorphic SNPs observed within the different test groups of Arctic charr.

The number of polymorphisms unique to each strain (Unique to strain) and the number shared with at least one other strain (Multiple strains) are shown. ‘Total recommended’ indicates markers classified as ‘recommended’ by the Axiom Analysis Suite’s best practices workflow. Polymorphic markers include the Axiom Analysis Suite, ‘polymorphic high resolution’ and ‘no minor homozygote’. Across the four groups, 79,692 unique SNPs were recommended for use.
