For biologists studying a large flatworm population in the lab, which Hardy-Weinberg condition is most difficult to meet?

A) no selection

B) no genetic drift

C) no gene flow

D) no mutation

Option A

Explanation:

Let us first understand the assumptions of Hardy Weinberg

Hardy Weinberg assumed the following for establishing his equilibrium equations –  

a)There must be no mutation

b)There must be random mating

c)There must be no gene flow,

d)Population size must be infinite and  

e)There must be no selection

Now, in case of studying a large flatworm population in the lab it is impossible to meet the following assumptions

a)Infinite population size –as the number of flatworm is fixed

b)There must be no selection – Though the population of flatworm is large even then the number of  unique individuals  is restricted as compared to that with in a wild population group of flatworm. Flatworm population is lab is more or less a selective population group only

c)There must be random mating – In a selective population group, the mating cannot be random  

Thus, option A is correct

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.
