The answer is size. The larger
the DNA molecule the slower it travels through the gel. This is because
of the restriction of their movement through the pores of the gel. The smaller DNA molecules travel furthest. The size
of the pores can be varied through by changing the mixture ratios of the agarose gel.

The cause of genetic drift is sampling error, which occurs when allele frequencies of a sample are different from the population due to random chance. It is a genetic phenomenon.
<h3>Genetic drift and allele frequencies</h3>
Genetic drift is a sampling error due to differences in allele frequencies of a sample from a population due to random chance.
Genetic drift is known to decrease the level of genetic variation of a given population.
Genetic drift is common in founder populations (e.g., island populations).
