Duplications D1 and D2 led to three paralogous clades encoding gbss, ssi, and ssii enzymes, and duplication D5 led to clades ssiii, and ssiv&ssv.
We detected positive selection in branch D1a (Table 1) in accordance with the new functions fulfilled by ssi and ssii when they diverged from gbss.
The simplest, ssus, is the proportion of the flock that is of the most highly susceptible genotypes (National Scrapie Plan (NSP) type 5; see table 1).
