Bottle effect biology

WebThe bottleneck effect describes the phenomenon when a population has a sudden reduction in the gene pool due to natural environmental events, natural disasters, disease, or human involvement. This reduction in the gene pool will likely cause a bias that did not exist in the original population. WebBottle Transformation. Imagine the image of a bottle. There are two parts: the neck and the body. What happens to the bottle when the body disappears and only the neck is left? A large portion of the bottle has transformed.
