Zoology (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

Invertebrate


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

  • Protozoa: Parasitism, conjugation and autogamy, medical importance.

  • Porifera: Canal system, skeletal structures and their taxonomic value, position of porifera in the Animal Kingdom.

  • Coelenterata: Polymorphism; measenteries corals and coral reefs.

  • Platyhelminthes: Parastic adaptations, medical importance

  • Nematoda: Medical importance.

  • Anneilda: Coelom, metamerism,

  • Mollusca: Shell, modifications of foot, feeding, respiration, shell fishery,

  • Arthropoda: Appendages, feeding: respiration, larvae.

  • Echinodermata: Skeleton, water vascular system, larvae.


PART - B

Chordata



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)



GENERAL ZOOLOGY


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 inclusions and cytoplasmic organelles, protein synthesis and molecular genetics. mechanism of mitosis and meiosis.



Part - B

.Part - C


Genetics: Mendelian principles, multiple alleles, interaction of genes: linkage and crossing over, mapping of genes, sex determination and sex linkage, mutations, chromosoinal aberrations, gene concept.


Part - D
