This chapter obtains DNA sequences from intron 7 of the beta fibrinogen gene for 21 taxa representing 14 genera of traditional neotomine-peromyscines, in order to examine phylogenetic relationships in the neotomine-peromyscine rodent complex. It observes that five main clades were consistently recovered, four of which correspond to previously recognized tribes: the Neotomini, Peromyscini, Baiomyini, and Tylomyini. The chapter further observes that the level of genetic divergence of Ochrotomys relative to other traditional peromyscines was higher (12.4%) than the comparison of Ochrotomys and the Neotomini (10.3%), and is similar to the comparison of the Baiomyini to the Peromyscini (11.7%). It notes that these results indicate that Ochrotomys may represent a separate tribe.
