I will give brainliest Chance events that cause allele frequencies to change result in genetic drift. Genetic drift becomes very important when the population size decreases. One type of genetic drift is the bottleneck effect. Explain how the bottleneck effect changes the population size and leaves to changes in allele frequencies and evolution

Explanation:

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.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
