Question

Match List I with List II :

List - I		List – II
A.	Gene pool	i.	Stable within a generation
B.	Genetic drift	ii.	Change in gene frequency by chance
C.	Gene flow	iii.	Transfer of genes into or out of population
D.	Gene frequency	iv.	Total number of genes and their alleles

Choose the correct answer from the options given below :

• A. A-III, B-II, C-I, D-IV
• B. A-IV, B-II, C-III, D-I
• C. A-I, B-II, C-III, D-IV
• D. A-II, B-III, C-IV, D-I

Answer 1

The Correct Option is B

A. Gene pool: A gene pool represents the total number of genes and their alleles present in a population. A-IV

B. Genetic drift: Genetic drift refers to random fluctuations in allele frequencies within a population due to chance events. This can lead to the loss of some alleles and the fixation of others. B-II

C. Gene flow: Gene flow is the transfer of genetic material (genes) between populations through migration. C-III

D. Gene frequency: Gene frequency refers to the proportion of a particular allele within a population. This frequency can be stable within a generation but can change across generations due to evolutionary forces. D-I
