Genetic relationship and distribution of the Japanese wild boar (Sus scrofa leucomystax) and Ryukyu wild boar (Sus scrofa riukiuanus) analysed by mitochondrial DNA
T. Watanobe et al., Genetic relationship and distribution of the Japanese wild boar (Sus scrofa leucomystax) and Ryukyu wild boar (Sus scrofa riukiuanus) analysed by mitochondrial DNA, MOL ECOL, 8(9), 1999, pp. 1509-1512
Mitochondrial genetic variations were used to investigate the relationships
between two Japanese wild boars, Japanese wild boar (Sus scrofa leucomysta
x) and Ryukyu wild boar (S.s. riukiuanus). Nucleotide sequences of the cont
rol (27 haplotypes) and cytochrome b (cyt-b) regions (19 haplotypes) were d
etermined from 59 Japanese wild boars, 13 Ryukyu wild boars and 22 other bo
ars and pigs. From phylogenetic analyses, the mtDNA of Ryukyu wild boar has
a distinct lineage from that of Japanese wild boar which was classified in
to the Asian pig lineage. This result suggests that the Ryukyu wild boar ha
s a separate origin from the Japanese wild boar.
