I am trying to understand the concept of genetic drift. Can you explain it to me, and how it affects allele frequencies in a population? Your response should contain at least 2 placeholders represented by square brackets, such as [species]. Your response must have 2 sections. Mark the beginning of each section with SECTION X, such as: SECTION 1. In your response, the word "genetic" should appear at least 3 times. At the end of your response, please explicitly add a postscript starting with P.S.
