Variation in gene frequencies within populations can occur by chance rather than by natural selection. This is referred to as:
Genetic load
Genetic flow
Genetic drift
Random mating
As discussed in
Genetic drift -
The term genetic drift refers to the etimation of the genes of certain traits when a section of population migrates or dies of natural calamity
- wherein
It alters the gene frequency of the remaining population
Option 1)

Option 2)
Genetic flow
This solution is incorrect
Option 3)
Genetic drift
This solution is correct
Option 4)
Random mating
This solution is incorrect
