Chapter 13 - Chromosomal rearrangements and changes in chromosome number. This chapter presents the following content: Rearrangements of DNA sequences, transposable genetic elements, rearrangements and evolution: a speculative comprehensive example, changes in chromosome number, emergent technologies: beyond the karyotype. | PowerPoint to accompany Genetics: From Genes to Genomes Fourth Edition Leland H.
