Question:
Populations with --------------- individuals have greater chances of genetic drift.
Populations with --------------- individuals have greater chances of genetic drift.
Show Hint
Chance changes in allele frequency matter most in small populations.
Updated On: Nov 12, 2026
- 100-150 million.
- 50-60 million.
- 5000-10000.
- 80-90 million.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Genetic drift is a change in allele frequencies purely by chance from one generation to the next.
Step 2: Effect of population size
In a very large population, chance changes cancel out. In a small population, a few chance events can eliminate or fix an allele.
Step 3: Compare the options
The options 50 to 150 million are huge populations. A population of 5000 to 10000 is far smaller.
Final Answer:
Populations of 5000 to 10000 individuals have the greatest chance of genetic drift. \[ \boxed{\text{(C) }\text{5000-10000.}} \]
