[i] Details of linkage maps can be found in the following papers: MARC97, Kappes et al. 1997; IBRP97, Barendse et al. 1997; IRRF95, Ma et al. 1996; and goat, Schibler et al. 1998.

[ii] For the comparisons using the IBRP97 or goat map, two sets of numbers are given. The first pertains to the overall number of markers on the IBRP97 or goat linkage maps, while the number in parentheses refers only to the number of markers on the IBRP97 or goat framework maps.
