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 leads
to changes in allele frequencies and evolution.

The bottleneck effect is an extreme example of genetic drift that happens when the size of a population is severely reduced.

Explanation:

a time line cause it goes from 685 to 978

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
