Introduction

  • Selection coefficient value (s) ranges between 0 and 1.
  • Hardy Weinberg equilibrium is p+q = 1
  • When each female has equal chance of mating with any male : Random Mating population %.
  • The number of sexually reproducing individuals in a population is called effective population.
  • Deme: Local inbreeding group consisting of series of individual genotypes
  • Polymorphism: Single gene showing various phenotypes
  • Inbreeding alters genotypes frequencies not gene frequency.
  • Specific DNA sequence for different enzymes are known as recognition sequence.
  • Ethidium bromide is used in southern hybridization for staining DNA.
  • Transfer solution is 0.4 M NaOH.
  • Selection is the main cause of genetic variability present in population.

 

Note:

a) DNA: Southern blotting ( DNA sequence or parential identification)

b) RNA: Northern blotting ( Disease resistance)

c) Protein: Western blotting ( To test bacteria and virus)
