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.
In addition to founder effects, the new population is often a very small population and so shows increased sensitivity to genetic drift, an increase in inbreeding, and relatively low genetic variation.s a result of the loss of genetic variation, the new population may be distinctively different, both genotypically and phenotypically, from the parent population from which it is derived. In extreme cases, the founder effect is thought to lead to the speciation and subsequent evolution of new species.
