If there  were no melanic forms in the pre-industrialisation era,what would be the end result of industrialization?

1.  Peppered moths would have increased in number

2.  Peppered moths would have become black due to the deposition of soor

3.  Extinction of peppered moths

4.  No change in the population of peppered moths

"Those who are better fit in an environment, leave more progeny than others." The evolutionary mechanism that operates for such a change is 

1. Natural selection

2. Genetic drift

3. Reproductive isolation

4. Polyploidy

2. Ramapithecus

3. Modern Homo sapiens

4. Neanderthal man

The following statements concerned with genetic drift are incorrect except one. Select the exception

1. Genetic drift maintains Hardy Weinberg equilibrium

2. Gene frequency in a small population change due to natural selections only

3. It is a change in gene frequency that occurs by chance in a small population

4. If gene migration happens multiple times, it is called genetic drift

Evolution is a 

1. Stochastic process

2. Discontinuous process

3. Reversible Process

4. All of these

Sudden heritable changes are called

1. Linkages

2. Mutations

3. Recombinations

4. Natural selection
