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.
Founder Effect: When a new colony of individuals is started from just a few members of the original population. All of the offspring will have the similar traits as the âfounders.â Genetic drift can cause big losses of alleles from the gene pool of small populations. When a population Population bottlenecks occur when a population's size is reduced for at least one generation.
