  1. Utilisation of non-protein nitrogen compounds in cow

  2. Role of modified fat in ruminants’ diet

  3. Mechanism of body defence against extreme cold and heat in cross-bred cows

  4. Phenotypic consequences of chromosomes mutation/aberrations

  2. Explain the relative differences that exist with respect to dietary essentiality of different vitamins between polygastric and mono-gastric livestock species.

  3. How does interaction that inherently exists between and among different mineral sources induce mineral imbalances, deficiencies and toxicities in different livestock species ? Furnish relevant examples to substantiate your answer.

Q.3

  2. Cytogenetics versus Molecular genetics

  3. Sex influenced versus Sex limited traits

  4. Genetic assortative versus Genetic disassortative mating

  5. Production traits versus Reproduction traits

  6. Tandem method of selection versus Selection index

Q.7

  1. What is the main effect of indreeding ? Does inbreeding as such increase the frequency of recessive genes ? Explain.

  2. Why do breeders in general, try to avoid inbreeding ?

  3. Illustrate with example how the genetic effect of inbreeding by using pair of genes (‘A’ for dominant; ‘a’ fo recessive allele) increases the homozygosity and decreases the heterozygosity in four generations by assuming that parent generation contains 1600 heterozygous individuals.
