Effect plots for combined (BXD24b × CAST) N2 + F2 mice. Allelic effects of (A) Cctq4 (Chr 3, rs3720779), (B) Cctq5 (Chr 11, rs3688569), and (C) Cctq6 (Chr 14, rs3707741). The numbers in parentheses are the numbers of mice with the indicated genotype. The numbers do not add up to the same value for (A–C) because of missing genotypes at that SNP for a variable number of mice. Asterisks denote P < 0.05 significance. Error bars: standard deviation.
