What happens when just a few organisms from a population start a new colony and there are only a small number of different alleles in the initial gene pool
The frequency of each allele in the new colony may be very differet to the frequency of those alleles in the initial population (eg a rare allele in original population maybe more common in new colony)
may lead to a higher incidence of genetic disease
The founder effect can occur as a result of what?
Migration, leading to geographical separation
or if a new colony is separated from the original population for another reason,
