Highlighting incomplete data. The same data displayed in the improved VIPER interface as in Figure 4B, in which 50% of F1 are genotypes are deleted. One of the wrongly assigned F1 littermates (175270) is highlighted in green. The addition of blue-border highlighting of incomplete genotype data points throughout the F1 progeny draws the user's attention to the possibility of error propagation by the algorithm. As seen in Figure 4B, the algorithm reports errors in the F2 progeny rather than in the mis-assigned F1 parents. Activating a 'Detail View' for descendants of 175270 shows the reporting of 'novel allele' errors in the F2 offspring.
