Table 5.
Regions containing shared unfavourable genotypes within the runs of homozygosity (ROH) between traits (interval from first to last insemination for heifers (IFL0), number of inseminations for heifers (AIS0), milk yield (MILK), protein yield (PROT) and fat yield (FAT) with P-values < 1.0e-05.
| Trait 1 | Trait 2 | CHR | Number of ROH genotypes | Position (Mb) | b on trait 1 (P-value) | b on trait 2 (P-value) |
|---|---|---|---|---|---|---|
| IFL0 | AIS0 | 17 | 2 | 9.21–10.59 | 10.5–12.8 (4.84e-08) | 0.26–0.28 (8.59e-07) |
| MILK | PROT | 3 | 3 | 52.83–56.18 | −321.6–−329.0 (3.11e-06) | −11.3–−11.7 (1.32e-07) |
| MILK | PROT | 13 | 83 | 44.37–58.55 | −145.5–−252.0 (1.23e-07) | −4.9–−8.8 (3.60e-10) |
| MILK | FAT | 13 | 1 | 57.32–58.55 | −207.3 (5.31e-07) | −6.6 (8.55e-06) |
| PROT | FAT | 13 | 1 | 57.32–58.55 | −7.6 (5.80e-09) | −6.6 (8.55e-06) |
Estimate b represents the difference between animals with the ROH genotype and animals without ROH (in days for IFL, in numbers of inseminations for AIS and in kg for MILK, PROT and FAT), while the P-value represents the smallest P-value for the region.
