For each LG information on the number (n) of marker pairs (intervals/segments) is given, which is also present as a marker pair (interval/segment) in A. mellifera (synteny). The genetic length in cM of the synthenic intervals/segments in B. terrestris (B.t.) and the corresponding intervals/segments in A. mellifera (A.m.) and the ratio between both species is given. Furthermore, the proportion (%) of synthenic marker intervals/segments of the total length of a B. terrestris LG is calculated. Likewise numbers of intervals/segments, their length (cM) and proportion (%) of the total length in B. terrestris is listed for intervals/segments of markers present in B. terrestris, but rearranged (not paired) on the matching A. mellifera LG ("homology"), indicating intrachromosomal rearrangements.
B. terrestris markers, which were found in a non-matching (see table 2) A. mellifera LG (interchromosomal rearrangement) are summed up as "inserts".
The last column shows the proportion (%) of synthenic plus homologous marker intervals/segments for each B. terrestris LG.
