Students who wish to pursue MS in genetics, molecular biology and/or biotechnology are the target group of readers for Part 2, in which fifteen lectures on topics like biological variations, polygenic inheritance, speciation, metabolic disorders in man, genetics of haemoglobin and human twins, Human Genome Project, human welfare, selection effects on animals, genetic control of pest insects and recent advances in Genetics and molecular biology have been dealt with. Lecture-wise contents, suggested reading and a huge number of illustrations and diagrams will help enrich the readers¿ thirst for an updated knowledge and understanding of Genetics.
