Artificial selection is the intentional reproduction of individuals in a population that have desired traits Ex: Improved race of Horse.

In a culture plate streptomycin resistant strain can be developed by using
1 Complete medium with streptomycin
2 Minimal medium and streptomycin
3 Only minimal medium
4 Only complete medium
Explanation:
If an organism has the ability to produce mutant strains resistant to antibiotics, the nature of mutation, whether it is spontaneous or induced have to be tested. Replica plating technique isolates both nutritional mutants and antibiotic resistant mutants. To develop antibiotic resistant strain we need a complete medium and a antibiotic.

Darwin's finches are best example of adaptive radiation which of the following best describe this adaptive radiation?
1 The evolutionary process that allows for the change that occur within the same lineage.
2 The genetic variability that can be found among individuals of same species.
3 A sudden diversification of a group of organism from closely related species.
4 The evolutionary process by which different forms, adapted to different niches, arose from a common ancestors.
Explanation:
The Darwins finches are an example of one ancestral species when moved to an isolated geographical location, undergo adaptation to meet their basic demands and evolve in different niches.

Darwinism explains all the following except:
1 Organisms tend to produce more number of offspring than can survive
2 Offspring with better traits that overcome competition are best suited for the environment
3 Variations are inherited from parents to offspring through genes
4 Within each species, there are variations
Explanation:
• The major draw back of Darwin's Theory of evolution was that he was not able to explain how variation among individuals originated and how they were transferred from parents to offspring.
