III. Lists of gene symbols
Gene symbols newly adopted and linkage relations newly confirmed are
listed. These are supplementary to those listed in RGN 1, 2 and 3. Because
of the delay of determination of a unified numbering system of chromosomes,
the numbering of linkage groups proposed by Kinoshita (see Table 4) is used in
the list.
