| QTL Experiment in Brief |
|---|
| Animals: | Resource flock of Indonesian Thin Tail sheep (ITT, known to have FecB mutation) crossed with Merino sheep. Nine families were created by backcrossing reciprocal ITT x Merino F1 to Merino ewes. |
| Breeds associated:
n/a
|
| Design: | 694 progeny were genotyped. Lambs reared to 500 days. Testicle weight with/without skin and live weight were measured at slaughter. 138 markers were analysed: 97.9 on average were informative per family. Mean male intermarker interval was 28.1cM. |
| Analysis: | General linear regression method with various fixed effects considered. Single QTL model analysis using the half-sib analysis of QTL Express (Haley and Knott, 1992). Chromosome-wide significance threshold was subject to permutation test (1000). |
| Software: | ITT map was constructed using Carthagene using already known lin |
