| QTL Experiment in Brief |
|---|
| Animals: | A total of 18 pigs were sequenced; 14 F2 sows (no full or half-sibs) of a cross between (Large White x Landrace) sows x Leicoma boars. 447 F2 sows with at least four litters, of which seven with extremely high and extremely low litter size were used |
| Breeds associated:
n/a
|
| Design: | Assay was developed on SNPs found at 3'UTR region for the CYP21 gene. Association analysis was performed on the 3 generation resources family on litter size traits. |
| Analysis: | Associations of genotypes with TNB and NBA were calculated by analysis of variance. All statistical analysis were performed with the SPSS program
(version 12.0). |
| Software: | SPSS |
