Genetic scientists accidentally create a new fish hybrid

Some experiments of a genetic type cannot but present a certain set of difficulties, because even if absolutely all the subtleties of such work are foreseen, researchers often face a lot of previously unforeseen circumstances. It is for this reason that a new random experiment of genetic properties from a gynogenesis specialist from the United States, associated with the crossing of the Russian sturgeon and the American paddlefish, caused such a huge stir in the modern world of genetics – after all, earlier even the most famous genetic scientists did not assume that this type of crossing with subsequent survival of the offspring is generally possible.
It is worth noting the fact that in this case we are talking about a truly random experiment, within the framework of which two representatives of two rather different fish species – the Russian sturgeon and the American paddlefish – were placed in a single controlled water space under laboratory conditions. First of all, their difference lies in the fact that the first is a rather aggressive predator, cracking down with great ease with crustaceans as the main food source, and the second is a typical lover of plankton and plant food under water.
However, at a certain point in time, a male American paddlefish released sperm, which interlocked with the eggs of a female sturgeon, resulting in a completely new hybrid type of fish that combines the DNA of both families. It was tentatively designated Sturddlefish, although the official name will probably be revised soon after even more detailed genetic research of the hybrid.
Moreover, after just two months, more than two-thirds of the main offspring remained alive, which clearly indicates an extremely stable and durable genetic code of both families, although earlier scientists-specialists in gynogenetics did not even assume that such different in habitat and type of evolutionary development fish in general can create strong and healthy hybrid offspring, and the current random experiment has clearly demonstrated this.
