Centric fusion: Fusion of the long arms of two acrocentric chromosomes [13,14,15,21,22] into a single chromosome having lost the short arms at the same time. Most often occurs as 21/21, 13/14, and 14/21 translocations.
If both arms are equal in length, the chromosome is said to be metacentric. Robertsonian -- fusion of 2 p arms by centric fusion to form metacentric chromosome.
