Answer: The given statement can be completed as-
Genetic variations in a population are caused by random mutation.
Genetic variations can be described as differences in the nucleotide sequence of genome ( genetic makeup ) of individuals that are present within a population.
They can be caused by random mutation ( permanent change in the nucleotide sequences) as it brings change in the frequency of gene in a population.
It can also be caused by crossing over between homologous chromosomes and random mating between organisms.
