Detailed explanation-1: -Translocations. A translocation occurs when a piece of one chromosome breaks off and attaches to another chromosome. This type of rearrangement is described as balanced if no genetic material is gained or lost in the cell. If there is a gain or loss of genetic material, the translocation is described as unbalanced .

Detailed explanation-2: -A genetic change in which a piece of one chromosome breaks off and attaches to another chromosome. Sometimes pieces from two different chromosomes will trade places with each other.

Detailed explanation-3: -In heredity: Translocations. If a chromosome break occurs in each of two nonhomologous chromosomes and the two breaks rejoin in a new arrangement, the new segment is called a translocation.

Detailed explanation-4: -Translocations. Translocations occur when chromosomes become broken during meiosis and the resulting fragment becomes joined to another chromosome.

Detailed explanation-5: -Robertsonian translocations A Robertsonian translocation occurs when one chromosome becomes attached to another.
