The two homologous chromosomal regions for each individual are shown arbitrarily as Left or Right. Q and wt mean the vertebral-number-increase allele and the wild-type allele, respectively.

a The same letters indicate identical haplotypes of the 57 markers within the 95% confidence interval.

b Heterozygosity was judged by t-test (** means P < 0.01).

c Homozygosity was judged by Z-score < -2.0, in which the Q-to-wt substitution effect was 0.49, as calculated with the data from nine heterozygotes in the Large White population.

d QTL type (Q/Q or wt/wt) was judged by multiple comparison analysis of vertebral number.
