Presentation Transcript

  1. Reproductive Strategies and Technologies

  2. Agriculture and Humans • Selective breeding • Artificial insemination • Embryo Transfer • In Vitro Fertilization • Cloning

  3. Selective Breeding Breeding of specific individuals in order to bring out a particular result. Where have you seen selective breeding?

  4. Artificial insemination The artificial transfer of sperm into a female reproductive tract

  5. Embryo Transfer • Embryos are artificially fertilized and then transferred to a surrogate. • Embryos are easy to ship • Animals a better survival if they stay where they were born, rather than imported.

  6. In vitro Fertilization Eggs and Sperm are combined together in a test tube. After fertilization, the embryo is transferred to the woman’s uterus

  7. Cloning The production of identical cells, genes or entire organisms.

  8. Gene Cloning Manipulating DNA to produce copies in foreign cells

  9. Therapeutic and Reproductive Cloning Involves Somatic Cell Nuclear Transfer

  10. Stem Cell Research • There are 3 sources for stem cells • Embryonic stem cells • Adult stem cells • Induced pluripotent stem cells • Controversy? • Solutions?

  11. Transgenic Organisms • The transfer of genetic material from one organism to another • Also known as genetically modified organisms • Benefits? • Concerns?

  12. Benefits • Safflower plant is being used to create insulin • Golden rice has a much higher nutrient value • Animals are being engineered to be better organ donors

  13. Issues • Ethical issues with animals being raised just for harvesting organs. • Transfer of genes to non-target species • Risk of transferring potentially harmful non-target genes
