Tandem repeats are an important part of the genome of all vertebrates. Specific features of the tandem repeats structural organization complicate the assembly, annotation, and mapping of heterochromatic chromosome regions that contain tandem repeats as the main component. The evolution of tandem repeats is also an extremely poorly studied issue. We compared sets of tandem repeats in two groups of vertabrates - true frogs (Ranidae) and hamsters (Cricetinae). We found that evolution of tandem repeats in different groups of vertebrates follows different paths and is caused by different mechanisms.
