Question:
Frequency of an allele in an isolated population may change due to
Frequency of an allele in an isolated population may change due to
Updated On: Jun 21, 2024
- Genetic drif
- Gene flow
- Mutation
- Natural selection
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Genetic drift refers to the random fluctuations in allele frequencies in a population due to chance events. In a small, isolated population, genetic drift can have a significant impact on allele frequencies.
So, the correct option is (A): Genetic drif

- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Concepts Used:
Frequency Distribution
A frequency distribution is a graphical or tabular representation, that exhibits the number of observations within a given interval. The interval size entirely depends on the data being analyzed and the goals of the analyst. The intervals must be collectively exclusive and exhaustive.
Visual Representation of a Frequency Distribution:
Both bar charts and histograms provide a visual display using columns, with the y-axis representing the frequency count, and the x-axis representing the variables to be measured. In the height of children, for instance, the y-axis is the number of children, and the x-axis is the height. The columns represent the number of children noticed with heights measured in each interval.
Types of Frequency Distribution:
The types of the frequency distribution are as follows:
- Grouped frequency distribution
- Ungrouped frequency distribution
- Cumulative frequency distribution
- Relative frequency distribution
- Relative cumulative frequency distribution
