Fig. 1From: Estimates of recent and historical effective population size in turbot, seabream, seabass and carp selective breeding programmesDecay of average linkage disequilibrium across chromosomes measured as r2 against physical distance. Physical distance in terms of fragment length is indicated in Mb for the species for which a physical map is available; i.e. turbot (left panels) and seabass (right panels). Three different distance categories are represented: a from 0.0 to 0.5 Mb; b from 0.5 to 5 Mb; c from 5 to 20 MbBack to article page
