Research
Julius' research interests lie in quantitative genetics and its application in animal breeding programs. Specifically:
Estimation of genetic parameters
- random regression models
- estimation of qtl - effects
Detection of quantitative trait loci
- designs of experiments
- QTL detection in meat sheep
- QTL detection for parasite resistance in sheep
Optimization of animal breeding programs
- complex breeding objective
- genetic algorithms
- marker assisted selection
- long term effects of selection
- selection methods vs finite locus models
