Haplotype analysis in the 95% confidence interval of the QTL on SSC7 in AY population. Haplotypes of microsatellite markers were analyzed in the nine sires and six dams in which allele types at the QTL (number-increase-type: Q or wild-type: wt) were determined. Microsatellite markers were genotyped with sires, dams, and their progeny, and haplotypes were reconstructed. The two homologous chromosomal regions for each individual are shown arbitrarily as Left (L) or Right (R). Numbers in each marker column represent allele types. Blocks of the same color are from the same IBD (identical-by-descent) region, which was supported by more than four markers. Italic characters indicate ambiguous alleles in determination of IBD regions. Blue letters indicate the haplotype of SJ7106 and SJ7101 conserved in the Q alleles. Red letters indicate distribution in the chromosomal regions of both the Q and the wt alleles. The candidate region contained three markers (SJ7106, SJ7101, and SJ7008) (white background in header row of table). Letters that are the same at the right of the panel indicate haplotypes that were identical at all 57 markers.
