Inherited disorders

• Polydactyly is caused by a dominant allele
• People with only one recessive allele for Cystic Fibrosis are carriers
• Genetic disorders can be detected through embryo screening during in vitro fertilization (IVF)
• There are arguments for and against embryo screening
• There are laws regulating embryo screening to prevent misuse
• For a child to have the disorder, both parents must be carriers or have the disorder themselves
• Many genetic disorders are inherited
• Embryo screening can help prevent people from suffering
• Embryos screening process

  1. Embryos are fertilized in a laboratory, then analyzed for genetic disorders before being implanted into the mother's womb

  2. Many genetic disorders can be detected through this process, such as cystic fibrosis

  3. DNA can also be extracted from embryos in the womb for testing

  4. Ethical, social, and economic concerns surround embryo screening

  5. Embryos with undesirable alleles may be destroyed after screening in IVF

  6. Screening embryos in the womb may lead to decisions to terminate the pregnancy
• Extra fingers or toes can be a symptom of Polydactyly
• Treating genetic disorders can be costly for the government and taxpayers
• Embryo screening may lead to controversial decisions
• Cystic Fibrosis is caused by a recessive allele
• Cystic Fibrosis is carried by about 1 person in 25
