(materials). A solvent in whose molecules there is either a permanent separation of positive and negative charges, or the centers of positive and negative charges do not coincide; these solvents have high dielectric constants, are chemically active, and form coordinate covalent bonds; examples are alcohols and ketones.1  Facebook.materials).

The bottleneck effect. The bottleneck effect is an extreme example of genetic drift that happens when the size of a population is severely reduced. Events like natural disasters (earthquakes, floods, fires) can decimate a population, killing most indviduals and leaving behind a small, random assortment of survivors.
Whats is the difference between Bottleneck Effect and Founder Effect in relation to inbreeding depression? It seems there is hardly any difference between the founder effect and bottleneck effect that leads to the same conclusion that the alleles in the population are not subject to change and over time recessiveness can be due to inbreeding.
