Which one of following scientists name is correctly matched with the theory put forth by him?

1. Weismann-Theory of continuity of germplasm

2. Pasteur- Inheritance of acquired characters

3. De vries-Natural selection

4. Mendel-Theory of pangenesis

Theory of inheritance of acquired characters was given by 

1. Wallace

2. Lamarck

3. Darwin

4. De Vries

In the case of peppered moth (Biston betularia), the black-coloured form became dominant over the light-coloured form in England during industrial revolution. This is an example of

1. natural selection whereby the darker forms were selected

2. appearance of the darker coloured individuals due to very poor sunlight

3. protective mimicry

4. inheritance of darker colour character acquired due to the darker environment

The first organisms were 

1. chemoautotrophs

2. chemoheterotrophs

3. autotrophs

4. eukaryotes

What was the most significant trend in the evolution of modern man (Homo sapiens) from his ancestors?

1. Shortening of jaws

2. Binocular vision

3. Increasing brain capacity

4. Upright posture

Origin of species' was written by 

1. Oparin

2. Weismann

3. Lamarck

4. Darwin

Which of the following is the most important precondition for speciation to occur?

(1) Reproductive isolation

(2) A crash of the population size

(3) Adaptive radiation

(4) Random mating

The ultimate source of allelic variations is:

1. Genetic recombinations 

2. Mutation 

3. Genetic drift 

4. Natural selection 

If a new allele suddenly becomes very abundant in a population, most likely it is:

1. mutating rapidly

2. flowing with emigrants

3. strongly selected for

4. a product of assortative mating

Genetic drift occurs when a few individuals of a species colonize an island. This phenomenon is :

(1) the bottleneck effect

(2) the founder effect

(3) assortative mating

(4) random mating
