I encountered this question before but it had choices. The missing choices of this question are:
A- immigration
<span>B-Natural selection </span>
<span>C- Random mutations </span>
<span>D- Geographic isolation
My answer would be C - RANDOM MUTATIONS.
A. Immigration is not applicable because it states There has been no migration in or out of the population in the last 200 years.
B. Natural selection is not applicable because of it states that the recessive allele frequency has been 0%.
D. Geographic isolation is not applicable because it is not a factor in the increase in the recessive allele frequency.
