parallel evolution

• the parallel evolution appears to occur mostly through the fixation of alleles of the same genes from the standing genetic variation in oceanic populations
• these alleles may be the product of single [93] or multiple [96] mutational events

• we used a novel and efficient genotyping approach based on Illumina sequencing of libraries of Restriction-site Associated DNA (RAD) tags
• it does not provide gametic phase across SNPs in different tags or haplotype sequence information
