Explanation:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Variation occur when there occurs defects and damages to DNA while being copied or passed onto the progeny.
For example...
Take very neat and clean sheet of white paper. Now just try giving this oaper in you class and aks them to pass it to others with doing nothing. When they're done take the sheet back and have a look at it.
Does it look the same as when you'd given it?
No, there will be minute or major changes.
This is exactly what happens to DNA too
