The products of these events appear multicolored following FISH assays.
These events have been remarkably common in the evolution of the accripitrids, causing an unusual pattern in the Sankoff-Ferretti model that contrasts with the distribution found in most birds. The products of these events appear multicolored following FISH assays. "Alternate" and "Adjacent 1" patterns result from these events due to pseudolinkage. The rapid evolution of genes like the histone variant CENP-A mediates the loss of parity caused by a form of meiotic drive in which a type of these events occurs because of selection against ending up in a polar body. That form involves the fusion of the "q" arms of  two acrocentric entities to form a metacentric one and is termed Robertsonian. The reciprocal type of these events involve the exchange of non-homologous material and includes the event that creates the Philadelphia chromosome. For 10 points, name these genetic aberrations involving part of one chromosome breaking off and attaching to another.
