Efficiency in detecting mappable SFP at the gene level (probe-set) and probe level by the ANOVA in comparison to the conventional linkage mapping approach
* In parentheses are indicated the percentage of genes or probes in common with those mapped by conventional linkage mapping considered as the benchmark approach
