  1. Genetic Diseases

  2. Genetic Diseases • Genetic Diseases can result from many things such as mutations in the gene or mutations in chromsome number • First lets recall a view facts…. • A female will have an two ____ chromosomes • A male will have an ___ and ___ chromosom • Also some diseases can be either __________ or sex-linked related

  3. Down Syndrome • Also known as Trisomy 21 • There is an extra 21st chromosome • This disease is an example of nondisjunction • Nondisjucntion - where the chromsomes fail to ________ during meiosis • Polyploidy -

  4. Short in stature • Will develop many health problems • Mental Retardation

  5. Turner Syndrome • Occurs in ________, they lack an X chromsome, so they are XO • Females will be short in stature, infertile, have a webbed neck, and low ears

  6. Klienfelter’s Syndrome • Occurs in ________ • They will be infertile • Tall, and possibly Mentally impaired

  7. Pedigree’s • Scientist used to study the inheritance patterns in a family and the possible offspring • Can be used to predict the possibility of disease

  8. Genetic Engineering “Dad, can you pass the genetically modified corn please?”

  9. Genetic Engineering • Can used in various ways – to create transgenic animals, to help with medicines, in forensics (crime solving), in crop production • Transgenic Organisms – contain genes from other ___________

  10. Glowing Fish

  11. Chickens engineered To have no feathers • Better poultry for the farmers

  12. Also transgenic plants • Plants and crops will be more resistant to harsh weather • Resistant to diseases • Resistant to insecticides

  13. Cloning • Making an exact copy – genetically • Will take DNA from the organism and place the DNA in an egg cell from another donor

  14. Dolly the sheep was The first successful Animal cloned

  15. Ethical Issues • Genetic Engineering raises many ethical concerns. • Ethical meaning right vs. wrong • Think about what makes genetic engineering ethical or unethical. • Write a paragraph about your position

  16. Other Applications • PCR – Polymerase Chain Reaction – making more DNA from small amounts – amplifying the DNA • Inserting human DNA into bacteria cells • Gene Therapy – replaces defective genes with normal genes
