Abstract
The Y centromere sequence of house mouse, Mus musculus, remains unknown despite our otherwise significant knowledge of the genome sequence of this important mammalian model organism. Here, we report the complete molecular characterization of the C57BL/6J chromosome Y centromere, which comprises a highly diverged minor satellite-like sequence (designated Ymin) with higher-order repeat (HOR) sequence organization previously undescribed at mouse centromeres. The Ymin array is approximately 90 kb in length and resides within a single BAC clone that provides sequence information spanning an endogenous animal centromere for the first time. By exploiting direct patrilineal inheritance of the Y chro..
