When a new population is established by a very small number of individuals from a larger population, sometimes becoming a different species, the process is called as:
1. Founder effect
2. Genetic bottleneck
3. Adaptive radiation
4. Convergent evolution

The process of evolution of different species in a given geographical area starting from a point and literally radiating to other areas of geography [habitats] is known as:

All the following are examples of evolution by anthropogenic action except:

Similar biological structures or sequences in different taxa are homologous if they:

The natural selection operating as shown in the given figure is called as:

1.	Disruptive
2.	Directional
3.	Stabilizing
4.	Retrogressive

Assume that 4 % of people in a population are born with sickle cell anemia [Sickle cell anemia is autosomal recessive]. What percentage of individuals will have the selective advantage of the sickle-cell trait?

In a population in genetic equilibrium, the frequency of the recessive allele is found to be 0.2. What is the frequency of heterozygotes in this population?

The phenomenon of the evolution of different species in a given geographical area starting from a point and spreading to other habitats is called:

A thorn of Bougainvillea and a tendril of Cucurbita are an example of :

Which theory, regarding the origin of life, is alternatively also called “panspermia”?
