| QTL Experiment in Brief |
|---|
| Animals: | A half-sib family was developed using one Brahman x Hereford sire. The sire was mated with MARC III (1/4 Hereford, 1/4 Angus, 1/4 Red Poll and 1/4 Pinzgauer) cows in 1996 to produce 259 offspring, of which 126 were
males. |
| Breeds associated:
n/a
|
| Design: | Body weight, scrotal circumference and testicular length in situ were obtained for each bull, using procedures described by Lunstra et al. (1988). |
| Analysis: | A total of 130 markers were used in the analysis for this study. Amplification reactions were performed with purified DNA extracted from blood with a saturated salt procedure. Amplification conditions have been described elsewhere (Kappes et al. 1997). |
