The lowest possible temperature, or absolute zero as it is called, is -459.67Â°F (-273.15Â°C). It is also called 0 kelvin, a scale with increments equivalent to degrees of Celsius, but which uses absolute zero rather than water's freezing point as its starting point.
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.
The term bottleneck is often used in conjunction with a manufacturing facility and refers to a point in the production process where product bunches up, then slows down or stops completely. For example, if two conveyor belts merge into one, the point where they merge is the bottleneck.
