There are some important variance in the rate of chromosomal rearrangement among species. These arrangements were included translocation, inversion...etc)
Noel Cabañas
The rate of chromosomal rearrangements is different among species, but there is a lot of factors that can influence this rate. In E.coli, for example, you will have about the one percent of your population with rearrangements after a generation, but you need to keep in mind that division bacterial is faster than eukaryotic organisms. Also, you have repair mechanism to contend with the damage in the DNA. There are a lot the factors that can influence the generation of rearrangements, even between species very closers like E. coli and Salmonella, these rates change. There are many kinds of rearrangements, the most known are deletions and insertions. But there is a lot of evidence about rearrangements like inversions and translocations, even rearrangements more complex that include combinations or intermediate steps. The inversions and translocations were known like rare events in the past, but nowadays, these are believed like frequent events and with great value for evolutionary events, for example, the most important changes between Chimpanzee and human genome are given by nine large inversions.
