Title
The collapse of gene complement following whole genome duplication.
Authors
Sankoff, David; Zheng, Chunfang; Zhu, Qian
Abstract
Genome amplification through duplication or proliferation of transposable elements has its counterpart in genome reduction, by elimination of DNA or by gene inactivation. Whether loss is primarily due to excision of random length DNA fragments or the inactivation of one gene at a time is controversial. Reduction after whole genome duplication (WGD) represents an inexorable collapse in gene complement.
