A genetic drift is a random change in allele frequency over time that is brought about by chances. A bottle neck is a drastic reduction in population size brought about by severe pressure.
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
That situation is called a Hardy-Weinberg equilibrium. Not actually seen outside of the lab.
The sudden change in the genetic make up or genetic form of an individual is called gene mutation.
Evolution; the change in allele frequencies over time in a population of organisms.
Sudden genetic change in the DNA of an organism called mutations.

It is called Mutation . It is a spontaneous change in a chromosome or DNA .
genetic traits
Random changes in allele frequency are due to genetic drift.
genetic variation
it is called a mutations
