Migration

Migration

  • Migration is the movement of individual into a population from a different population. Migration may introduce new alleles into the population or may change the frequency of existing allele. The amount of change in gene frequency ‘q’ will primarily depend upon two factors.
      a. Ratio of migrant individuals to those of the original population.
      b. The Magnitude of difference between the values of q in the population and in the migrants.
      So in plant breeding migration is by inter varietal crosses or poly crosses.
