Robertsonian translocation

(Science: molecular biology) A special type of nonreciprocal translocation in chromosomes whereby the long arms of two nonhomologous acrocentric chromosomes are attached to a single centromere.

The short arms become attached to form a reciprocal structure that however often disappears some divisions after its formation.
