Genetic Drift - the constant changing of allele frequencies (that percentage of all alleles any one, or more, allele occupies in a population) in a population over time, due to random mating. 
 
Random Mating - has the effect of changing how frequently an allele is found in a population. 
GENETIC DRIFT IS RANDOM, ALWAYS DRIFTING UP AND DOWN 
 
bottlenecks - where a gene pool is significantly reduced for some reason and a relatively small allele diversity remains.

Genetic Drift 
 
Refers to the ongoing variation in allele frequencies within a population over time due to 
random mating events. Genetic drift causes allele frequencies to fluctuate randomly. 
 
Random Mating 
Influences allele frequencies by altering how often specific alleles appear within a 
population. This process is inherently unpredictable, with allele frequencies increasing or 
decreasing randomly.
