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 bottleneck effect is _______________. a sudden reduction in population size due to a change in the environment. The resulting gene pool may no longer be reflective of the original populationâs gene pool. If the population remains small, it may be further affected by genetic drift. Genetic drift is significant in small populations.
