Match types of variation in column I with their causes in column...
Match types of variation in column I with their causes in column II. Select the correct option.
| Column I | Column II |
|---|---|
| A. Gene mutation | I. occurs due to crossing over |
| B. Gene recombination | II. caused due to natural disasters |
| C. Gene flow | III. sudden permanent heritable change |
| D. Genetic drift | IV. migration of organisms |
Options
- AA-III, B-I, C-II, D-IV
- BA-III, B-I, C-IV, D-II
- CA-I, B-II, C-III, D-IV
- DA-I, B-III, C-II, D-IV
Correct answer
B. A-III, B-I, C-IV, D-II
Step-by-step solution
Gene mutation is a sudden, permanent, and heritable change in the genetic material.
Gene recombination occurs due to crossing over during the pachytene stage of meiosis I.
Gene flow is the transfer of genetic variation from one population to another, which occurs due to the migration of organisms.
Genetic drift is the change in the frequency of an existing gene variant in a population due to random chance events, often caused by natural disasters (bottleneck effect).
Thus, A matches with III, B matches with I, C matches with IV, and D matches with II.
