Fig. 4From: Comparative genomics and association analysis identifies virulence genes of Cercospora sojina in soybeanGenome-wide average linkage disequilibrium (LD) decay over physical distances based on 38,725 SNP markers. The half LD decay distance was 3.7 kb when the LD declined to 50% (r2 = 0.48) of its initial value. kb, kilo base pairsBack to article page
