polyploidy
bullet::::- endopolyploidy occurs when in adult differentiated tissues the cells have ceased to divide by mitosis, but the nuclei contain more than the original somatic number of chromosomes. in the "endocycle" (endomitosis or endoreduplication) chromosomes in a 'resting' nucleus undergo reduplication, the daughter chromosomes separating from each other inside an "intact" nuclear membrane. in many instances, endopolyploid nuclei contain tens of thousands of chromosomes (which cannot be exactly counted). the cells do not always contain exact multiples (powers of two), which is why the simple definition 'an increase in the number of chromosome sets caused by replication without cell division' is not quite accurate.this process (especially studied in insects and some higher plants such as maize) may be a developmental strategy for increasing the productivity of tissues which are highly active in biosynthesis. the phenomenon occurs sporadically throughout the eukaryote kingdom from protozoa to humans; it is diverse and complex, and serves differentiation and morphogenesis in many ways.
karyotype
ranallo was absent from wwe commentary beginning with the march 14, 2017 episode of "smackdown live", including missing wrestlemania 33. wwe first claimed that ranallo had missed a show due to travel issues associated with the march 2017 north american blizzard. when ranallo missed another show a week later, wwe said he was ill. ranallo reportedly missed the shows due to depression, with one alleged reason for the illness (supported by ranallo's close friend bas rutten from mixed martial arts) being bullied by fellow commentator john "bradshaw" layfield. on wwe's "bring it to the table" show, jbl had mocked ranallo for tweeting about winning the "best announcer" award from the "wrestling observer newsletter". on march 24, ranallo tweeted, "i'm deeply touched by your tweets of support. my doctor wants me to stay off social media for now but i wanted to thank you." cbssports.com reported in april, citing an unnamed source, that ranallo was not expected to return to wwe's television programming. wwe did not confirm this, but told cbssports.com that ranallo's contract was valid until august 12, 2017. wwe subsequently removed mentions of ranallo from their social media websites, and ranallo also removed mentions of wwe from his twitter account. angered wwe fans called on wwe to fire layfield, with some even claiming they cancelled their wwe network subscriptions in protest. ranallo's alleged treatment by layfield as well as revelations from ring announcer justin roberts's autobiography resulted in a scandal for wwe because of their refusal to stop backstage harassment. on april 22, "newsweek" reported that ranallo and wwe "mutually agreed to part ways", and ranallo released a statement in which he said his departure had "nothing to do with jbl."
