Table 3 Heart rate distributions, according to the genotype (BN/SHR, BN/SHR, or SHR/SHR), for the APOA02, R1106, and R830 markers that flanked the heart rate QTL mapped in a 188 F2 (SHR × Brown Norway) population.

From: Genetic mapping of a new heart rate QTL on chromosome 8 of spontaneously hypertensive rats

  1. *p < 0.05 when compared to BN/BN.
  2. Note that heart rate effect (bpm) represents the heart rate difference between BN/BN and SHR/SHR genotypes.
