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.
A founder effect occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have: 1  reduced genetic variation from the original population. 2  a non-random sample of the genes in the original population.
