Presentation Transcript
agriculture and humans
Agriculture and Humans
  • Selective breeding
  • Artificial insemination
  • Embryo Transfer
  • In Vitro Fertilization
  • Cloning
selective breeding
Selective Breeding

Breeding of specific individuals in order to bring out a particular result.

Where have you seen selective breeding?

artificial insemination
Artificial insemination

The artificial transfer of sperm into a female reproductive tract

embryo transfer
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.
in vitro fertilization
In vitro Fertilization

Eggs and Sperm are combined together in a test tube.

After fertilization, the embryo is transferred to the woman’s uterus

cloning
Cloning

The production of identical cells, genes or entire organisms.

gene cloning
Gene Cloning

Manipulating DNA to produce copies in foreign cells

therapeutic and reproductive cloning
Therapeutic and Reproductive Cloning

Involves Somatic Cell Nuclear Transfer

stem cell research
Stem Cell Research
  • There are 3 sources for stem cells
    • Embryonic stem cells
    • Adult stem cells
    • Induced pluripotent stem cells
    • Controversy?
    • Solutions?
transgenic organisms
Transgenic Organisms
  • The transfer of genetic material from one organism to another
  • Also known as genetically modified organisms
  • Benefits?
  • Concerns?
benefits
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
issues
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
