Gene duplication and evolution.
Lynch and Conery (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 the subsequent halflife of duplicates. These two parameters are of particular importance in studying the evolutio...
متن کاملSimulating evolution by gene duplication.
By considering the recent finding that unequal crossing over and other molecular interactions are contributing to the evolution of multigene families, a model of the origin of repetitive genes was studied by Monte Carlo simulations. Starting from a single gene copy, how genetic systems evolve was examined under unequal crossing over, random drift and natural selection. Both beneficial and deter...
متن کاملGene duplication and the evolution of phenotypic diversity in insect societies.
Gene duplication is an important evolutionary process thought to facilitate the evolution of phenotypic diversity. We investigated if gene duplication was associated with the evolution of phenotypic differences in a highly social insect, the honeybee Apis mellifera. We hypothesized that the genetic redundancy provided by gene duplication could promote the evolution of social and sexual phenotyp...
متن کاملEvolution of Gene Duplication in Plants1[OPEN]
Ancient duplication events and a high rate of retention of extant pairs of duplicate genes have contributed to an abundance of duplicate genes in plant genomes. These duplicates have contributed to the evolution of novel functions, such as the production of floral structures, induction of disease resistance, and adaptation to stress. Additionally, recent whole-genome duplications that have occu...
متن کاملMolecular Evolution of MDM1, a “Duplication-Resistant” Gene in Vertebrates
BACKGROUND The mouse double minute 1 (Mdm1) gene was first reported and cloned in mouse tumor cell lines as an oncogene candidate. Later, it was found that mutation of Mdm1 might cause age-related retinal degeneration 2 in mice by genetic linkage analysis. Additionally, the MDM1 protein was found to be expressed in the centrosomes, cilia, and the nucleus of multiciliated tracheal epithelial cel...
