Figure 2From: Genetic mapping of a new heart rate QTL on chromosome 8 of spontaneously hypertensive ratsRat chromosome 8 heart rate QTL in 188 rats from an F2 intercross (SHR × Brown Norway) population. The horizontal dashed line denotes the likelihood ratio (LR) of 11.5 as the threshold for suggestive linkage. See Table 3 for details of markers delimiting the QTL and the effects on heart rate, according to genotype.Back to article page
