Unit 9A: Inheritance and selection

QCA

Resources

Resources include:

  • pictures of large family groups from which inherited characteristics can be identified
  • secondary sources giving information about variation, reproduction and selective breeding in animals and plants, including different varieties of plant
  • graphics software for producing graphs illustrating variation in a sample
  • CD-ROMs on plants, eg a gardening reference work
  • software simulations or video clips showing gametes and fertilisation and how animal and plant cells pass on genetic information
  • information leaflets about breeds of farm animal
  • information about cloning and genetically modified organisms (GMOs) from environmental groups and farming and governmental organisations
  • plant specimens, eg common fruits and vegetables, showing variation such as size, shape and colour
  • wind- and insect-pollinated flowers and photomicrographs of pollen and ovules
