long distance mobility of male japanese macaques evidenced by mitochondrial dna.a 487-nucleotide sequence in the polymorphic d-loop region of matrilineally inherited mitochondrial dna was compared in samples from 14 (9 adult males and 5 females or young) japanese macaques (macaca fuscata fuscata) of two troops at gagyusan in takahashi city, okayama prefecture, japan. the majority (7 out of the sampled 9) of the adult males associated with the troops had nucleotide sequences of six distinct types, all of which were different from that of the gagyusan troop females, whereas t ...200312548337
