EtOH-induced LORR. a EtOH-induced LORR in S1 was greater than that in B6, F1, or F2, and greater in F2 than that in B6. b F2 LORR scores were somewhat bimodally distributed (dashed line is normal distribution), with many values around 60 min and another cluster around the cutoff of 180 min. c A scan for single-locus main effects using the two-part model found a significant main-effect locus on Chr 4 and a suggestive locus on Chr 6. d The locus has an S1 dominant effect. e Regression revealed a sex difference in the allelic effect of this locus such that males with the S1 alleles had the highest LORR duration; *P < 0.05.
