Detailed explanation-1: -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: -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-3: -In a translocation, a segment from one chromosome is transferred to a nonhomologous chromosome or to a new site on the same chromosome. Translocations place genes in new linkage relationships and generate chromosomes without normal pairing partners.
Detailed explanation-4: -A chromosomal defect in which a segment of the chromosome breaks off and reattaches in the reverse direction.
Detailed explanation-5: -The four main types of structural chromosomal aberrations are deletion, duplication, inversion, and translocation.
