REPETITIVE DNA. "The chromosomal localization of repetitive DNA was previously thought to be only a result of selection, but recent findings show that other factors such as targeting of TEs into specific chromosomal niches are also important." (TE = transposable elements). https://lnkd.in/gdTbmHn View in LinkedIn

JUMPING GENES. "Even closely related species often significantly differ in composition of their transposable elements or satellites." https://lnkd.in/gdTbmHn View in LinkedIn

"REPETITIVE DNA forms a significant proportion of eukaryotic genomes. This is particularly evident in plants, which have faster genome dynamics than animals." https://lnkd.in/gdTbmHn View in LinkedIn

DRIVER AND RESPONDER REQUIRED. "Zygotic drive of the autosomes has been observed in a wide diversity of model organisms (e.g., worms, beetles, and mice). In general, an autosomal zygotic driver must have both a driver allele at one locus and a protective allele at a responder locus." http://cshperspectives.cshlp.org/content/7/3/a017608.full View in LinkedIn

FOOTNOTE. ""Zygotic drive is an unusual form of genetic conflict because it directly reduces Darwinian fitness by killing or debilitating offspring. It is favored by gene-level selection when there is competition among siblings for limiting resources. By killing or weakening noncarrier competitor siblings, the gene(s) coding for zygotic drive gain a selective advantage because their survival is increased at the expense of siblings carrying alleles that are not identical by descent—despite any fitness loss to the parents, siblings, or other parts of the genome." http://cshperspectives.cshlp.org/content/7/3/a017608.full View in LinkedIn

GENOMIC CONFLICT 4: "De novo mutations can also gain a transmission advantage by increasing the rate of stem cell division in the germ line (germline drive)." http://cshperspectives.cshlp.org/content/7/3/a017608.full View in LinkedIn

MALEABLE RELATIONSHIPS. “Strong environmental pressures can also shape pathobiomes, and turn otherwise pathological interactions into mutualistic relationships.” https://lnkd.in/gEfVGaC View in LinkedIn

BIOLOGICAL TABOO. "In terms of the driving force, it is tempting to consider dioecy as simply the most extreme mechanism which avoids the deleterious effects of inbreeding." https://lnkd.in/gb3zS32 View in LinkedIn

GLOBALIZATION AND CROSSING. “The current predominantly poultry-associated clones have most probably emerged after a human-to-poultry host jump, estimated to have occurred ~50 years ago, and which rapidly disseminated worldwide thanks to the globalization of the poultry industry.” https://lnkd.in/gEfVGaC View in LinkedIn

BARRIER TO SELF-POLLINATION. "Dioecy prevents intra-individual self-pollination absolutely, while monoecy merely prevents intra-flower self-pollination but not intra-individual self-pollination." https://lnkd.in/gb3zS32 View in LinkedIn
