In a translocation a segment of a chromosome becomes attached to a non-homologous chromosome. In reciprocal translocations, two non-homologous chromosomes exchange segments. Translocation also includes exchange between non-homologous parts of a pair of chromosomes, e.g. between X and Y chromosomes. There is no addition or loss of genes during translocations, only a rearrangement. Translocations are due to irregularities during crossing over. Breaks in the chromosomes are followed by union in ways different from the normal condition. In translocation homozygotes breaks occur in both chromosomes of two different chromosome pairs, and there is mutual interchange of segments.
