*Measured from the 5' end of the first segment to the 3' end of the last segment. ^†Locus 2 contains a single segment with protein tyrosine phosphatases (PTPs) and two segments with ankyrins (anks). ^‡Characteristics of regions of these loci that were not sequenced were hypothesized based on the equivalent locus in the other (GiBV or GfBV) genome.
