Abstract
Satellites from two related species of the Apodemus genus, A. sylvaticus and A. flavicollis, have been analysed with restriction enzymes Taq I, Alu I and Hind III. The restriction maps are closely conserved between species and show a novel feature of two differing internal periodicities within a 375 base pair repeating unit detected by two different restriction enzymes. This places constraints on the introduction of the observed restriction sites according to current models such as unequal crossing-over. The implications of such a conserved sequence and its presence in other species are discussed.
