From: CENP-A binding domains and recombination patterns in horse spermatocytes
Model for double-spotted centromeres in horse pachytene. On the left, two homologous chromosomes (maternal M and paternal P) with different centromeric position within satellite DNA arrays characterized by different numbers of satellite repeats. On the right, possible scenarios after homolog pairing: centromeres remain too close to be resolved separately (a) or become sufficiently distant to be visualized as stretched (b) or double-spotted (c) signals.
