Why is the founder effect an example of genetic drift?

In genetics, a founder mutation is a mutation that appears in the DNA of one or more individuals which are founders of a distinct population. Founder mutations initiate with changes that occur in the DNA and can be passed down to other generations. Any organism—from a simple virus to something complex like a mammal—whose progeny carry its mutation has the potential to express the founder effect, for instance a goat or a human.
