Genetic variation in the vulnerable and endemic Monkey Puzzle tree, detected using RAPDs.

abstract：:Complete D-loop sequences of 20 Mus from three localities in Turkey and seven in Iran were characterized. These countries are thought to be close to the place of origin of the subspecies Mus musculus domesticus. Five new M. m. domesticus haplotypes were added to the nine already known for the region. Four of these 14 ...
