WebThe portions exchanged are known as ‘translocated segments’ and the rearranged chromosome is called a ‘derivative’, reported as ‘der’, and is named according to its centromere. Provided that there is no loss of genetic material, the translocation is balanced (i.e. no loss or gain of genetic material) and usually results in normal development. WebJun 23, 2011 · The mechanisms of the generation of the variant translocations are not fully clear; some authors have suggested 2 different mechanisms: a 1-step mechanism in which chromosome breakage occurs simultaneously on 3 or 4 different chromosomes in 3-way or 4-way translocation, respectively, and a 2-step mechanism involving 2 sequential …
