Total Marks – 200
Paper I
Marks – 100

Invertebrate and chordate zoology
The candidates will be required to attempt five questions – three from Part A and two from Part b
Part A
General organization (general morphology, mode of life, adaptations, life cycles and economic
importance) of the following groups with special reference to the topics mentioned in each group:
1. Protozoa: Parasitism, conjugation and auto gamy, medical importance
2. Porifera: Canal system skeletal structures and their taxonomic value, position of porifera in the
animal kingdom
3. Coelenterata: Polymorphism, measenterics, corals and coral reefs
4. Platy helminthes: Parasitic adaptations, medical importance
5. Nematode; Medical importance
6. Aunelida: Coelum, metamerism
7. Mollusca: Shell, modifications of foot, feeding, respiration, shell fishery
8. Echinodermata: Skeleton, water vascular system, larvae
9. Anthropoda: Appendages, feeding, respiration, larvae
Part B
Origin, comparative account of skeleton, circulatory, excretory and nervous systems, development (Egg
types, cleavage, blastula and gastrula, germ layer / formation, embryonic membranes and placentation)
natural history (mode of life, migration, adaptations, biting mechanism of snakes)
Paper II
Marks – 100
The candidates will be required to attempt at least one question from each part
Part A
Cell biology: Morphology, chemical composition and functions of nucleus, nuclear inclusion and
cytoplasmic organelles, protein synthesis and molecular genetics, mechanism of mitosis and meiosis
Part B
General physiology: Respiration, respiratory mechanism, respiratory pigments, transport of oxygen and
carbon dioxide, circulation. Haemodynamics, control of cardio vascular system, nutrition, modes of
nutrition, digestion and assimilation of food stuff. Excretion – nature and sources of substance excreted,
modes of excretions, nervous system, nerve impulses, hormones and their biological action
Part C
Genetics: Mendelian principles, multiple alleles, interaction of genes – linkages and crossing over,
mapping of genes, sex determination and sex linkages, mutations, chromosomal aberrations, gene
Part D
Evolution: Origin of life, organic diversity, theories to account for organic diversity, Phylogeny and
ontogeny, species concept, mechanism of evolution, modern concept of natural selection, evolutionary
Part E
Ecology: Concept of Ecosystem, biochemical cycles, animal adaptations to major habitats, environmental
pollution and its effect on life.
