. Define the following:

1. Conservation genetics  

2. Wider endemic  

3. In situ conservation  

4. Inbreeding  

5. Fragmentation  

6. H-W law  

7. Speciation  

8. Founder Effect  

9. Critically Endangered  

10. Additive variation  

Answer the following questions

1. List anthropogenic factors which increase the rate of extinctions in animals  

2. How these are linked to extinctions: inbreeding depression, genetic drift, fragmentation, purging  

3. What are the methods by which genetic diversity is measured.  

4. Classify total variance.  

5. If a human population has M, MN and N type of blood group individuals as follows:  

   34500, 53000 & 2400. Check whether the gene frequencies are in equilibrium. How many heterozygotes are there. If N allele is lethal in pure form, what shall be the realised gene frequency.
