707.	State Hardy – Wein berg principle of genetic equilibrium knowing that genetic drift disturbs this equilibrium. Mention what does this disturbance in genetic equilibrium lead to?
Answer» Hardy Weinberg principle states that allele frequencies in a population are stable and remain constant from generation to generation. Genetic drift refers to a change in allele frequencies of a population acquiring by chance. Such a change in allele frequency may be so different that the population becomes a different species. The original drifted population is called founder and the effect is called founder effect.

742.	How do Darwin’s finches illustrate adaptive radiation?
Answer» Darwin finches are varieties of small black birds found in the Galapagos islands. They all must have evolved in the island itself. From the original seed eating birds, many other forms evolved, with altered beak enabling them to become insectivorous and vulgarian habits. This process of evolution of different species in the same geographical area starting with one spices and radiated to other areas is called adaptive radiation.
