The third allele of supernatant isocitrate dehydrogenase of house mouse, iId-1c, originates from asian continent.

Genetic differentiation of U.S.S.R. house mice: electrophoretic study of proteins

“…The involvement of both Mus-2C and Mus-2A is shown by variation at the Sod-1 locus, and within 300 km to both north and south (39, 53) we find other markers from both 2A and 2C. As in Japan (Minezawa et al, 1980), a mixing of gene pools of these founding groups appeared to take place here. However, in contrast to their east neighbours (Mus-2B) Primorye mice do not possess morphological and ecological characteristics which would allow us to distinguish them with certainty from castaneus.…”

Geographical survey of protein variations in wild populations of Japanese house mouse, Mus musculus molossinus.

“…Interregional differences are revealed by two distributional patterns of several alleles. Es-2a, Es-2b, Amy-1a, Amy-2a and Prt-1a were distributed more frequently in the peripheral regions as did Hbbd allele , and Es-5b, in the southern regions as Id-1a and Id-1c (Minezawa et al 1980). In relation to the insufficiency of the number of examined loci and mice in each locality, the calculation of the average heterozygosity of seven Western Hemisphere house mouse populations and their subpopulations, Mus musculus musculus of the northern Denmark population, M. m. domesticus of the southern Denmark Therefore, it may be said that the genetic variability of the Japanese wild mouse population is not different from the other mouse populations.…”

“…where x~1 means the frequency of the i-th allele at the l-th locus and r implies the number of loci examined. Table 2 shows the average heterozygosity of Japanese wild mouse populations calculated with 12 loci including Hbb ) and Id-1 (Minezawa et al 1980). In the overall Japanese population, the average heterozygosity (H) shows extremely high variability, H= 0.298.…”

“…When H values were calculated for each region where a relatively Table 2. Genetic variability in the Japanese wild mouse, estimated by the average heterozygosity (H) * Calculation was carried out based on 12 loci , Es-1, Es-2, Es-5, Es-6, Amy-i, Amy-2, Prt-1, Prt-2, Mod-i, Trf, Hbb , and Id-i (Minezawa et al 1980). ** Calculation was carried out based on 7 loci , excluding Es-6, Amy-1, Amy-2, Prt-i and Prt-2 loci from above 12 loci.…”

“…Several alleles, Es-1°, Es-id, Es-2g and Es-5°, found in Japanese populations were not reported in Western Hemisphere populations, except for rare cases in Hawaiian populations (Wheeler and Selander 1972), whereas these alleles except for were commonly observed in Asian mice in addition to Hbbp and Id-1c (Nishimura 1977;Minezawa et al1978Minezawa et al ,1979Minezawa et al and 1980Minezawa et al unpublished data). These findings may suggest the close ralationship between Japanese and Asian mice, and also the possible contribution of the Asian mouse to the Hawaiian mouse population.…”
