Fig. 1From: Detection and replication of QTL underlying resistance to gastrointestinal nematodes in adult sheep using the ovine 50K SNP arrayResults of linkage analysis (LA; a, b) and combined linkage disequilibrium and linkage analysis (LDLA; c, d) genome scans performed for the two indicator traits of parasite resistance analyzed. Analyzed traits: LFEC Log-transformed faecal egg count, IgA t Box-Cox-transformed optical density ratio (ODR) values of immunoglobulin A activity. Likelihood ratio test (LRT) values obtained across the 26 ovine autosomes are represented. For those chromosomes that harbor significant QTL, the horizontal lines indicate the 5 % chromosome-wise significance threshold for LA (a, b) and the 5 % chromosome-wise significance threshold for LDLA (c, d)Back to article page
