HEYA!
Genetic drift :
Genetic drift is the change in the frequency of an existing gene variant in a population due to random sampling of organisms.
Genetic drift example :
A disease comes into the rabbit population and kills 98 of the rabbits. The only rabbits that are left are red and grey rabbits, simply by chance. The genes have thus “drifted” from 6 alleles to only 2. This is an example of a bottleneck effect
Hope it helps uhh ❗️
