| QTL Experiment in Brief |
|---|
| Animals: | The granddaughter design consisted of 14 paternal half-sib families with an average number of 128 and a range of 33 to 313 sons per sire, with sire denoting the male parent common to each half-sibship. |
| Breeds associated:
n/a
|
| Design: | Seven traits (milk yield, fat yield, protein yield, fat percentage, protein percentage, length of productive life, and somatic cell score) were considered in the analysis. |
| Analysis: | Marker data were available on 246 microsatellite markers. Of these, 222 were assigned to the 29 autosomal chromosomes. The statistical methods employed for QTL mapping were least-squares analysis and variance components analysis. |
| Software: | Cri-Map |
