Polyploidy as a Selection Method

Polyploidy as a Selection Method

Biology Presentation & amp; quot-Selection & amp; quot- (Grade 9)

The topic of the usefulness / harmfulness of GMOs is one of the top ones if you decide to debate in a motley company. Strange – humanity so dreamed of conquering hunger, but when real tools appeared to fulfill its plan, a wave of protests and prohibitions arose. Arguments and counterarguments in matters related to GMOs are analyzed by Daniil Gladkikh, a junior researcher at the Institute of Chemical Biology and Fundamental Medicine of the SB RAS, and a popularizer of science.

To start the story about organisms whose genotype was artificially altered using genetic engineering methods, in my opinion, it is best with dinosaurs and Jack Horner. First of all, dinosaurs are cool. Secondly, the first is enough. So, in narrow circles of paleontologists and adolescents, Horner is widely known for providing convincing evidence back in the 1970s that some dinosaurs cared for their offspring, built nests and were flocked. He also developed the following hypothesis – the tyrannosaurus was a scavenger scavenger, not an active predator – and this became the cause of one of the most intense and protracted disputes in the history of paleontology. Friendship won, and now it is believed: the tyrannosaurus was an opportunistic predator – he could both hunt and eat carrion. However, the press ignored this theory, and we have a media image of a tyrannosaurus solely as a brutal aggressive killer predator. In fairness, I note that some part of this image was introduced by Jack Horner himself – he was a friend of the director Steven Spielberg, a consultant to the film Jurassic Park and the prototype of the paleontologist Alan Grant, but the moral of the story is different. As we can see, without the proper level of coverage, some aspects of truth can be hidden forever in the shadow of provocative headlines – and this applies primarily to genetically modified organisms.
