Fig1. Illumina Infinium Protocol on Bead Array: After WGA amplification (Whole Genome Amplification) and fragmentation, the DNA is hybridized to probes (attached to beads) of each of the genetic variations investigated. An extension step of a labelled nucleotide confers allelic specificity. Genotyping is performed using GenomeStudio software, which determines the genotype for a given variant based on the ratio of colors detected
