How would a founder event influence allele frequencies and diversity in a new population?

How would a founder event influence allele frequencies and diversity in a new population?

• A. A subset of alleles is represented, leading to reduced genetic variation and potentially different allele frequencies due to sampling
• B. No change in allele frequencies; same as source
• C. Increase in diversity due to new mutations
• D. Complete fixation of all alleles

Answer: (A)
