Although gene duplication has generally been viewed as a necessary source of material for
the origin of evolutionary novelties, the rates of origin, loss, and preservation of gene …

The importance of gene duplication in supplying raw genetic material to biological evolution
has been recognized since the 1930s. Recent genomic sequence data provide substantial …

Gene and genome duplications have given rise to enormous variability among species in
the number of genes within their genomes. Gene copies have in turn played important roles …

Immediately after a gene duplication event, the duplicate genes have redundant functions. Is
natural selection therefore completely relaxed after duplication? Does one gene evolve …

Gene duplication events are important sources of novel gene functions. However, more
often than not, a duplicate gene may lose its function and become a pseudogene. What is …

Gene duplication has generally been viewed as a necessary source of material for the origin
of evolutionary novelties, but it is unclear how often gene duplicates arise and how …

Newly emerging data from genome sequencing projects suggest that gene duplication, often
accompanied by genetic map changes, is a common and ongoing feature of all genomes …

What are the evolutionary consequences of gene duplication? One answer is speciation,
according to a model initially called Reciprocal Silencing and recently expanded and …

Gene and genome duplications are commonly regarded as being of major evolutionary
significance. But how often does gene duplication occur? And, once duplicated, what are the …

Gene duplication is an important mechanism for acquiring new genes and creating genetic
novelty in organisms. Many new gene functions have evolved through gene duplication and …
