ezRAD is from the family of RAD (restriction site associated DNA) techniques that cuts up the DNA (either by sonication or restriction enzymes) and looks at large areas of the genome, as apposed to the whole genome. RADseq data often forms stacks of DNA on the same loci\u00a0(vertical coverage of the genome). These stacks are then used to find SNPs\u00a0(single-nucleotide polymorphisms). The interesting difference with ezRAD compared to other RAD techniques is that it utilizes a frequent cutting enzyme and so the data produced not only forms vertical stacks but also horizontal coverage across other regions of the genome. This makes the data more tricky to analyse, but it does mean that with this technique we can easily annotate our loci and get almost 100% of the mitochondrial genome, ribosomes and histones (i.e. high copy regions).
