Harvy Weinburg and Evolution

Cards (6)

  • Definition of a species.
    A group of similar organisms that can reproduce to give fertile offspring
  • Definition of a population.
    A group of organisms of the same species occupying a particular space at a particular time that can potentially interbreed.
  • Definition of a gene pool.
    The complete range of alleles present in a population in a given time
  • Definition of allele frequency.
    The number of times a particular allele occurs within the gene pool
  • Organisms in a population have the same genes but different combinations of alleles.
  • What does the Harvy Weinburg principle predict ?
    That the proportion of dominant and recessive alleles of any gene in a population remains the same from one generation to the next provided five conditions met :
    1. No mutations
    2. Isolated population
    3. No natural selection
    4. Large population size
    5. Random mating
