Worked Solution & Example Answer:Genetic drift is A - VCE - SSCE Biology - Question 16 - 2002 - Paper 1
Step 1
C. random changes in the gene pool of a population.
Answer
Genetic drift refers to the random fluctuations in allele frequencies that occur in a population. Unlike natural selection, which favors certain traits based on their advantages for survival, genetic drift occurs by chance. This process is particularly significant in small populations where random events can greatly affect the gene pool, leading to the loss or fixation of alleles. Therefore, option C accurately describes genetic drift.
