Detailed Solution

Repetitive DNA sequences are thought to have no direct coding function.

Repetitive DNA can help to define the structure of chromosomes by providing points at which chromosomes can be anchored or by forming large blocks of DNA that contribute to the overall structure of the chromosome.
In terms of chromosome dynamics, repetitive DNA can play a role in chromosome rearrangements which can result in the creation of new gene combinations.
Changes in the distribution or expression of repetitive DNA can lead to reproductive isolation and the formation of new species. Repetitive DNA can also contribute to the evolution of new traits through the process of gene duplication and the creation of new gene families.
