“…Genome haploidization involves sequential loss of cohesin from chromosome arms and centromeres during two meiotic divisions. At centromeres, cohesin's Rec8 subunit is protected from separase cleavage at meiosis I and then deprotected to allow its cleavage at meiosis II. …”

“…It was found that the gender dichotomy is reinforced in the classroom, causing tensions and stereotyped divisions for male and female roles. Various forms of violence have been reproduced by classmates and teachers, who, due to lack of knowledge or to unpreparedness, reinforce concepts and attitudes that lead to the maintenance of exclusion. …”

“…We demonstrate that clonal dominance can emerge spontaneously, in the absence of pre-existing biases, as a collective property of evolving excitable networks through coupling of divisions among connected cells. Similar mechanisms have been identified in forest fires and evolving opinion networks [9–11]; we show that the spatial coupling of excitable units explains a critical feature of the development of the organism, with implications for tissue organization and dynamics [1,12,13].…”
