Mardi Gras-a carnival held in some countries on Shrove Tuesday (the last day before Lent) but especially in New Orleans.
Bottleneck effect is when there's something that either kills the majority of the population or just prevents it from reproducing. This creates genetic drift because the likelihood of gene prominence changing is much higher in a small population. The Founder Effect is a type of Bottleneck effect. It is when a small amount of individuals starts a population usually due to migration.
That's the bottleneck effect. The bottleneck effect is a sharp lowering of a population's gene pool because of an environmental, or human-caused, change. It might turn out to be an advantage to the red jelly bean as the environment changes, but it also might not be.
