Mendelian inheritance

Generally applies to qualitative characters

Some examples:

  • Is the plant resistant to fungus x or not?
  • Is the flower red or white?
  • Does the plant need a certain daylength to flower or not?
  • This situation arises when a trait is controlled by one (or a small number of ) "major" genes.

    There are many examples of this in breeding:

  • Disease resistance
  • Dwarfness
  • Flower colour
  • These characters are often quite easy for the breeder to handle by simply looking at the phenotype
