Question:
Statement I: The change in frequency of a gene that occurs merely by chance and not by selection in small populations is called genetic drift.
Statement II: The existence of deleterious genes within the population is called genetic load.
Statement I: The change in frequency of a gene that occurs merely by chance and not by selection in small populations is called genetic drift.
Statement II: The existence of deleterious genes within the population is called genetic load.
Show Hint
Genetic Drift = Random chance; Genetic Load = Carrying "bad" genes.

- Both statements I and II are true
- Both statements I and II are false
- Statement I is true but II is false
- Statement I is false but II is true
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Population genetics.
Step 2: Analysis
* Statement I is true: Genetic drift is the change in allele frequency due to chance in small populations. * Statement II is true: Genetic load refers to the accumulation of deleterious recessive genes in a population.
Step 3: Conclusion
Both statements are true.
Final Answer: (A)
Population genetics.
Step 2: Analysis
* Statement I is true: Genetic drift is the change in allele frequency due to chance in small populations. * Statement II is true: Genetic load refers to the accumulation of deleterious recessive genes in a population.
Step 3: Conclusion
Both statements are true.
Final Answer: (A)
