| QTL Experiment in Brief |
|---|
| Animals: | Six F0 Landrace boars, 11 F0 Hampshire sows and the entire F2 generation (320 animals) were genotyped. In addition, 60-79 unrelated animals from four breeds (Landrace, Yorkshire, Hampshire, and Duroc) were also genotyped for association study. |
| Breeds associated:
n/a
|
| Design: | In this study, we present an investigation of MC4R as a candidate gene for the fat/meat QTL. We also evaluate the Asp298Asn polymorphism as an underlying target in the selection for daily gain in Danish pig populations. |
| Analysis: | Based on the SNP genotypes, MC4R was included in the existing sex-averaged SSC1 linkage map and with the MC4R genotype
included in the QTL analysis model as a fixed effect. |
| Software: | CRI-MAP version 2.4; QTL Express. |
