Duplication of haemoglobin genes
Biochimie, 1972Resume L'etude de l'hemoglobine humaine a ete particulierement fructueuse dans la definition des genes de structure. La reconnaissance du fait que plus d'un locus peut intervenir dans le controle genetique d'une chaine polypeptidique a conduit a reexaminer certaines idees generalement acceptees.

Gene Duplication and Evolution
Science, 2001Lynch and Conery ([1][1]) presented one of the first serious efforts to study the evolutionary fate of gene duplication using genomic sequence data. Their analysis led to several interesting observations, particularly with respect to the rate of gene duplication in eukaryotic genomes and ...

Human Mutation, 2006
The detection of duplications in Duchenne (DMD)/Becker Muscular Dystrophy (BMD) has long been a neglected issue. However, recent technological advancements have significantly simplified screening for such rearrangements. We report here the detection and analysis of 118 duplications in the DMD gene of DMD/BMD patients.

Retention of duplicated genes in evolution
Trends in Genetics, 2022Gene duplication is a prevalent phenomenon across the tree of life. The processes that lead to the retention of duplicated genes are not well understood. Functional genomics approaches in model organisms, such as yeast, provide useful tools to test the mechanisms underlying retention with functional redundancy and divergence of duplicated genes ...

Gene Duplication and Evolution
Science, 2002Abstract Motivated in part by Ohno’s (1970) influential book, substantial attention has been given to the idea that gene duplication is a major mechanism for the origin of new gene functions. A theoretical population genetic framework for understanding the evolutionary mechanisms responsible for the success versus demise of gene ...

Current Opinion in Genetics & Development, 2001
Genomic sequencing projects have revealed the productivity of processes duplicating genes or entire chromosome segments. Substantial proportions of the yeast, Arabidopsis and human gene complements are made up of duplicates. This has prompted much interest in the processes of duplication, functional divergence and loss of genes, has renewed the debate ...

Duplicated homeobox genes in Xenopus
Developmental Biology, 1989Multiple kinds of clones and restriction fragment polymorphisms are frequently encountered when analyzing genes of the tetraploid frog Xenopus laevis. Two types of cDNA clone have been isolated for homeobox gene 2. Analysis of their corresponding genomic clones confirmed the existence of clearly distinct restriction maps; in addition the nearby ...

The evolutionary demography of duplicate genes
Journal of Structural and Functional Genomics, 2003Although 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 duplicates are not well understood. Applying steady-state demographic techniques to the age distributions of duplicate genes censused in seven completely sequenced genomes ...

Gene Duplication and Gene Loading
2014During the early evolution of life, gene duplication, the production of two copies of a DNA sequence, allowed the rapid diversification of enzymatically catalyzed reactions and an increase in genome size, providing also material for the invention of new enzymatic properties and complex regulatory and developmental patterns. A duplication may involve (i)

Preservation of duplicate genes by originalization
Genetica, 2008Neofunctionalization, subfunctionalization and increasing gene dosage were proposed to be the possible ways to explain duplicate-gene preservation in previous studies. However, in some natural populations, such as yeast Saccharomyces cerevisiae, a considerable proportion of the duplicate genes originated from ancient whole genomic duplication (WGD) is ...
