Breeding Populations and Mating Systems |
|
- Gene and genotype frequencies in random mating populations (Hardy-Weinberg
equilibrium and assumptions)
- Two loci (gametic phase equilibrium)
- Changes in gene frequency due to selection
- Coancestry and inbreeding
- From pedigrees
- Regular systems of inbreeding

Quantitative Genetics – Mean Performance
of Populations |
|
- Components of phenotypes
- Genotypic values
- Average effect of a gene
- Breeding values
- Selection of parents
|
4 |
Quantitative Genetics – Phenotypic and
Genetic Variances |
| |
- Genetic variance: additive and dominance
- Environmental variance
- Covariance between relatives
- Heritability
- Genetic and phenotypic correlations
|
5-6 |
Estimation of Genetic Parameters |
|
- Variance components
- From paired matings and other family structures used in breeding
programs
- North Carolina Designs I, II, III
- Parent-offspring regression
- Generation means analysis
- Realized heritability from selection experiments
- Designs for detecting
epistasis
- Complex pedigrees – BLUP, ML vs REML estimation
- GCA and SCA
- Diallel analyses
- Testcross trials (progeny trials)
- Degree of dominance, heterosis,
inbreeding depression
|
7-8 |
Selection Response |
| |
- Expected gain from selection
- Breeding inbred lines and hybrids: testcross selection, predicting
performance of hybrids and synthetics
- Family index - combining information from relatives
- Selection for multiple traits (other types of selection indices)
- Indirect selection with correlated characteristics
- Marker assisted selection
