Molecular markers come in all forms. Since actual base-pair distances are generally hard or impossible to directly measure, physical maps are actually constructed by first shattering the genome into hierarchically smaller pieces. Predicting quantitative traits with regression models for dense molecular markers and pedigree. Simulation studies have shown that a few thousand markers are enough to accurately estimate heritability [ 57 ], and inclusion of causative SNPs has little effect on prediction accuracy [ 58 ]. The cost-benefit is also likely to be most favorable for traits that cannot be measured on potential breeders e. The use of lower density SNP or the combination of low density SNP and an imputation strategy may help to reduce genotyping costs without compromising gain in reliability.

This process is often referred to as " positional cloning ", and it is used extensively in the study of plant species The great advantage of genetic mapping is that it can identify the relative position of genes based solely on their phenotypic effect.
The essence of all genome mapping is to place a collection of molecular markers onto their respective positions on the genome.

The required number of fish from all families were tagged individually at an average weight of The use of a low marker density panel may represent a cost-effective approach for GS prediction especially for aquaculture where thousands of potential breeders need to be genotyped. Skip to main content Skip to sections. The quality control step resulted in a total of individuals and 49, SNPs distributed across the genome for further analysis.

Nevertheless, previous studies in the same commercial Atlantic salmon population used in the present study estimated moderate to medium heritability 0.

|Conclusions These results indicate that genomic predictions can accelerate genetic progress for SRS resistance in Atlantic salmon and implementation of this approach will contribute to the control of SRS in Chile.
By analyzing the fingerprints, contigs are assembled by automated FPC or manual means pathfinders into overlapping DNA stretches.
