This week's Nature contains the paper on the completion of the
sequence of human Chr. 2 & 4 with more details about the head to head
telomere remnants and the remains of the lost centromere (in the
section on Segmental Duplications. Segments close to telomeres tend
to be duplicated to the near-telomere or near-centromere regions of
other chromosomes. Sure enough, there are segments on either side of
the telomere fusion region which were duplicated to the expected
regions of other chromosomes before the fusion occurred.
