GENE CONNECTEDNESS. "New genes gradually evolve broader expression patterns and therefore acquire pleiotropic functions, as they gradually evolve more linking partners, and genes with more linking partners tend to have broader expression patterns." https://genomebiology.biomedcentral.com/articles/10.1186/s13059-015-0772-4 View in LinkedIn

GRADUAL INTEGRATION. "The integration of new genes into GGI networks is a gradual evolutionary process. The new genes started, at a young age, to be integrated into networks to form new and less connected branches; however, with the elapse of evolutionary time, as genes grow older, they acquired more interacting links." (GGI = Gene-gene interaction networks)." https://genomebiology.biomedcentral.com/articles/10.1186/s13059-015-0772-4 View in LinkedIn

DEATH OF DE NOVO GENES. "The high rate of de novo gene birth in combination with a rather constant number of genes over time predicts that many of the de novo genes have only a short lifetime." http://www.sciencedirect.com/science/article/pii/S0168952515000347 View in LinkedIn

TRIUMPH OF DUPLICATION. "Speciation by genome duplication was recognized early in the study of evolutionary genetics and “represented the first major triumph in the genetics of speciation”. http://scholar.google.com/ View in LinkedIn

TWO KEY SEQUENCES. "Transcriptional regulatory sequences are as important for gene function as the coding sequences that determine the linear array of amino acids in a protein." https://lnkd.in/dTi6Znf View in LinkedIn

DYNAMIC PROCESS. "While gene family evolution is pervasive, it may be especially important in our own evolution since it appears that the "revolving door" of gene duplication and loss has undergone multiple accelerations in the lineage leading to humans." http://www.ncbi.nlm.nih.gov/pubmed/19153999 View in LinkedIn

NEUTRAL VARIATION. "There appear to be many ways that phenotypes are buffered from perturbation by genotypic and environmental variation (2 ± 4) and, in fact, selectively neutral genetic variation is widespread." https://lnkd.in/duMqB2A View in LinkedIn

ALTERNATION OF GENERATIONS. "In 1851, Hofmeister recognized that plants alternate be- tween two distinct phases, yet it was not until 1894 that Strasburger proposed that this ‘‘alternation of generations’’ represented an alternation between haploid and diploid phases. Such an alternation of generations is a necessary consequence of sexual reproduction, since a haploid phase must follow meiosis and a diploid phase must follow gamete fusion, but the lengths of these two phases vary widely among organisms." An important article. https://lnkd.in/d_wyEN8 View in LinkedIn

HAPLOID-DIPLOID DIVIDE. "Sexual eukaryotic organisms are characterized by an alternation between haploid and diploid phases. In vascular plants and animals, somatic growth and development occur primarily in the diploid phase, with the haploid phase reduced to the gametic cells. In many other eukaryotes, however, growth and development occur in both phases, with substantial variability among organisms in the length of each phase of the life cycle." https://lnkd.in/d_wyEN8 View in LinkedIn

DIPLOID WINDOW. "Widespread and abundant variation is maintained in a selectively neutral form within the genetic architectures of eukaryotes, particularly those with an extended diploid phase of the life cycle." https://lnkd.in/duMqB2A View in LinkedIn
