Zoology-Hardy-Weinberg Principle
NEET Zoology Hardy-Weinberg Principle Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): In a population at Hardy-Weinberg equilibrium, allele frequencies do not change over generations. | Reason (R): Genetic drift can cause significant changes in allele frequencies in small populations.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option B
Detailed Explanation
The Hardy-Weinberg principle states that allele frequencies remain constant in a population over generations, which is true. However, genetic drift affects small populations and is not the reason allele frequencies remain constant under Hardy-Weinberg equilibrium.
