Severe Phenotypes of Chromosome 6 Congenic Intervals (Histology Scores 5 + 6)
| Interval | Locus | N/N vs. total N/N (%) | N/P vs. total N/P (%) | P/P vs. total P/P (%) |
| I | D6Mit21–11 | 63/149 (42) | 28/63 (44) | 17/29 (58.6) |
| II | D6Mit11–25 | 77/206 (37) | 36/71 (51) | 18/29 (62) |
| III | D6Mit25–26 | 99/247 (40) | 40/73 (55) | 15/35 (43) |
[i] Numbers of animals are reported for the corresponding genotype for each genetic interval. Percentages are calculated vs. the total number of animals observed for each genotype.
