  • In Carlson's detailed biography of Muller, the only mention of Muller's work in speciation is a relatively brief mention of his studies on the genetic basis of sterility in hybrids between Drosophila melanogaster and D. simulans ( C arlson 1981 , pp. 280-281). (genetics.org)
  • gene
  • The results suggested that the Hmr must have functioned as a suppressor gene other than hybrid lethal suppression in the process of speciation (Watanabe). (nii.ac.jp)
  • 4)A speciation gene, Lhr of D.simulans was examined whether it rescued hybrids carrying a deficiency of D.melanogaster in the hybrid. (nii.ac.jp)
  • Genetic driftrefers to random changes in gene frequencies that usually occurs in a small population and results from chance processes alone. (topperlearning.com)
  • Ecological speciation with gene flow is widespread in nature , but it presents a conundrum: how are associations between traits under divergent natural selection and traits that contribute to assortative mating maintained? (fredhutch.org)
  • Individual chapters provide concise overviews of the many flavors of plant transposons and of their roles in gene creation, gene regulation, development, genome evolution, and organismal speciation, as well as of their epigenetic regulation. (wiley.com)
  • evolution
  • We often hear about new 'genome sequences,' commercial kits that can tell you about your ancestry (including pre-human) from your DNA or disease predispositions, debates about the truth of evolution, why animals behave the way they do, and how people found 'genetic evidence for natural selection. (coursera.org)
  • Most interestingly, we are engaged in uncovering evidence of genetic conflict involving segregation distorters as a driving force in the evolution of hybrid sterility during the earliest stages of speciation. (utah.edu)
  • Plasticity is an important consideration for studies of speciation in nature, and this topic promises fertile ground for integrating developmental biology with ecology and evolution. (hindawi.com)
  • genomic
  • The combination of two or more genomes of different origin in the first-generation hybrids is usually accompanied by a phenomenon referred to as genomic shock, which results in different genetic and epigenetic changes. (springer.com)
  • epigenetic
  • In the limiting case of fully stable epialleles our approach reduces to the classical theory of experimental line crosses and thus illustrates a fundamental continuity between genetic and epigenetic inheritance. (genetics.org)
  • ecology
  • However, it is unclear whether a general relationship exists among latitude, climatic zonation and the ecology of speciation. (nlbif.nl)
  • geographic
  • These data support the concept that speciation in the order Scorpaeniformes, in most cases, follows a geographic mode through accumulation of numerous small genetic changes over a long period of time. (springer.com)
  • diversification
  • However, observed patterns are rarely compared with those obtainable with simple null models of diversification under stochastic lineage birth and death and random genetic drift. (pnas.org)
  • widespread
  • Speciation slowing down in widespread and long-living tree taxa: insights from the tropical timber tree genus Milicia (Moraceae). (umich.edu)
  • evolutionary
  • Second, we are applying evolutionary theory to the problem of identification of the genetic architecture of underlying cancer development. (yale.edu)
  • For example, segregation distorters are selfish genetic elements that subvert the mechanisms of meiosis to over-represent themselves in gametes, thus gaining a massive evolutionary advantage. (utah.edu)

  • process
  • It is only when the real data are statistically different from the expectations under the null model that some speciation process should be invoked. (pnas.org)
  • studies
  • Taken together, we recommend the presented birth−death model as a null hypothesis in prokaryotic speciation studies. (pnas.org)
  • Recent taxon-specific studies obtained different results regarding the role of climate in speciation in tropical versus temperate areas. (nlbif.nl)
  • clusters
  • Our initial phylogeographic analysis revealed that there is only one major area of contact between coastal and interior lineages and identified five genetic clusters with strong spatial structuring: Pacific Slope, Interior US, Edwards Plateau (Texas), Northern Mexico, and Southern Mexico. (ku.edu)
  • adaptation
  • Furthermore, a polygenic genetic model that explains adaptation to contrasting benthic and limnetic feeding niches also predicted F2 female mate choice. (fredhutch.org)
  • However
  • However, little is known little about the neurological and genetic basis of host choice generating RI. (nd.edu)
  • natural selection
  • Terms like "environment," "speciation," "plasticity," and "natural selection" are sometimes assumed by different workers to have different definitions, and this can affect communication [ 38 ]. (hindawi.com)
  • Genetic change in response to natural selection and resulting in organisms with improved performance with respect to some function or feature of the environment. (hindawi.com)
