| QTL Experiment in Brief |
|---|
| Animals: | Pigs were from several experimental populations: Landrace and Large White composite selected for litter size (Nebraska Index Line); commercial Duroc x Hampshire F1; and UNL resource population originating from commercial Large White x Landrace rotational cross or NIL dams and commercial maternal Landrace sires.
Animal breed (IDs) involved: 283�528�526�301 |
| Breeds associated:
|
| Design: | Animals were genotyped using the Illumina PorcineSNP60 BeadChip and analyzed for litter size traits. Four complementary approaches for detecting selective sweeps based on allelic and haplotype diversity were integrated with GWAS. |
| Analysis: | A Bayes B approach was used for GWAS. In addition, F(ST) and relative extended haplotype homozygosity (REHH) were calculated. |
| Software: | JMP, PLINK, FastPHASE, Sweep, R software, Gensel |
