Bottlenecks and Founder Effects. Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a populations size is reduced for at least one generation.ottlenecks and Founder Effects.

Chernobyl, or Chornobyl, is the name of a city situated in northern Ukraine near the border with Belarus. Chernobyl was largely abandoned following the disaster at the Chernobyl Nuclear Power Plant located 14.5 kilometres (9 miles) away.
Chernobyl was a nuclear power plant in the former Soviet Union. On 26 April 1986, it suffered a massive failure which caused it to spread radioactive waste across large parts â¦ of Europe.    The accident began with a steam explosion that caused a fire, more explosions, and a subsequent nuclear meltdown.he disaster at Chernobyl is considered to be the worst nuclear disaster in history. One of the nuclear reactors at the plant had a meltdown, and spewed toxic, â¦ radioactive fallout all over Chernobyl and the surrounding areas. Practically half of Russia and Europe were affected.
