The sequence of the mouse genome allows one to compare the conservation of synteny between the human and mouse genome and exploration of regions that might have been involved in major rearrangements during the evolution of these two species (evolutionary genome rearrangements). Recent segmental duplications (or duplicons) are paralogous DNA sequences with high sequence identity that account for...
Several recent studies have focused on the evolution of recently duplicated genes in Drosophila. Currently, however, little is known about the evolutionary forces acting upon duplications that are segregating in natural populations. We used a high-throughput, paired-end sequencing platform (Illumina) to identify structural variants in a population sample of African D. melanogaster. Polymerase c...
Changes in gene copy number are among the most frequent mutational events in all genomes and were among the mutations for which a physical basis was first known. Yet mechanisms of gene duplication remain uncertain because formation rates are difficult to measure and mechanisms may vary with position in a genome. Duplications are compared here to deletions, which seem formally similar but can ar...
