    • What type of disorders can be inherited from parents?
      Some genetic disorders
    • What can be screened for in embryos?
      Many inherited disorders
    • What causes Cystic Fibrosis?
      A recessive allele
    • What effect does Cystic Fibrosis have on the body?
      It produces thick, sticky mucus
    • Why are individuals with one copy of the recessive allele considered carriers?
      They do not show symptoms of the disorder
    • What must be true for a child to have Cystic Fibrosis?
      Both parents must be carriers
    • What happens if either parent has Cystic Fibrosis?
      Their children will also have the disorder
    • What is the probability of a child having Cystic Fibrosis if both parents are carriers?
      1 in 4 chance
    • What is Polydactyly?
      A genetic disorder with extra fingers or toes
    • What type of allele causes Polydactyly?
      A dominant allele
    • Can Polydactyly be passed on if only one parent carries the allele?
      Yes, it can run in the family
    • What is the chance of a child having Polydactyly if one parent has the allele?
      50% chance
    • What is the process of in vitro fertilisation (IVF)?
      Embryos are fertilised in a laboratory
    • What can be done to embryos before implantation during IVF?
      A cell can be removed and analysed
    • Which genetic disorder can be detected through embryo screening?
      Cystic Fibrosis
    • What is a controversial aspect of embryo screening?
      Ethical issues surrounding the process
    • What happens to embryos with 'bad' alleles after screening?
      They would be destroyed
    • What could screening lead to for embryos in the womb?
      Decision to terminate the pregnancy
    • What are the arguments for embryo screening?
      • Helps families choose healthy embryos
      • Reduces suffering from severe disorders
      • Saves government healthcare costs
      • Allows parents to select traits
    • What are the arguments against embryo screening?
      • Ethical concerns about 'playing God'
      • Potential for discrimination based on traits
      • Risk of social pressure to screen
      • Limits on parental choice
    • What is a potential outcome of embryo screening for parents?
      Choosing a healthy embryo
    • What is a concern regarding the cost of treating disorders?
      It costs the Government a lot of money
    • What is a limitation regarding sex selection of babies?
      Cannot select unless for health reasons
    • What is a good practice suggested in the material regarding embryo screening?
      Writing a balanced argument for and against
    • What is the question posed at the end of the material?
      Why wouldn’t all carriers for the cystic fibrosis allele have the disorder?
