What are chromosome inversions? Inversions are a diverse class of chromsomal mutation. The majority are small (<1KB) .Others, for example the famous 3RP inversion of Drosophila melanogaster, are several megabases in size, include several percent of the entire genome and span hundreds or thousands of genes ..
