What is Evolution That Occurs as a Result of Chance

Question

What is evolution that occurs as a result of chance events?
A) sexual selection
B) genetic drift
C) gene flow
D) population bottleneck

Accepted Answer

Genetic drift is evolution that occurs as a result of chance events, such as random fluctuations in allele frequencies due to small population size or random mortality events. This can result in the loss of certain alleles or the fixation of others, leading to genetic differences between populations over time.
