| QTL Experiment in Brief |
|---|
| Animals: | DNA samples were obtained from the Cooperative Dairy DNA Repository bor bulls comprising 2 half-sib families. Sire 1 had 96 sons and sire 2 had 212 sons. |
| Breeds associated:
n/a
|
| Design: | Multiple traits were measured falling into 4 groups: the udder group, the body form group, the feet and legs group, and the dairy capacity group. |
| Analysis: | Half-sib regression based on least squares using the program QTL Express was used to analyse each sire family individually under a granddaughter design model to estimate the segregation status of each sire. |
| Software: | Genoprob and QTL Express |
