Abstract:

Gene duplication is universal across all organisms and plays a key role in driving the evolution of genomes and genetic systems. The fate and mechanism of gene duplication is hotly debated and involves the advantages and disadvantages of gene duplicates, retention bias of daughter copies, divergence of evolution rates and expression patterns,and factors that determine the preservation of duplicated genes. Here, we briefly introduce advances in research into gene duplication and discuss the main issues.
