Artificial Selection/Selective Breeding: Process of selecting organisms with desired traits to be parents of the next generation. 2 Forms:
Biotechnology: Humans select desirable traits specifically for industry, agriculture and medical purposes.
Human Genome Project: This project identifies the DNA sequence of every gene in the human genome (a genome is all the DNA in one cell of an organism). This will have many medical and ethical implications and is incredibly controversial...
- Inbreeding: Involves crossing 2 individuals that have SIMILAR characteristics
- Hybridization: Breeders cross 2 genetically DIFFERENT individuals in hopes that the offspring will take on BOTH traits.
Biotechnology: Humans select desirable traits specifically for industry, agriculture and medical purposes.
- Cloning: Offspring are genetically identical to the organism from which it was produced.
- Artificial Reproduction: Reproductive technology is used to form a zygote. 2 processes include artificial insemination (sperm is "harvested" and inserted into a female organism for reproduction) and in vitro fertilization (sperm and ova are harvested and then combined in a lab setting. Embryos are then implanted in a parent host)
- Genetic Engineering: The DNA of organisms are altered when genes from one organism are transferred into the DNA of another organism.
- Gene Therapy: Copies of a gene are directly inserted into the cells of a human

Genetic Modification: Is It Ethical?

CHECKPOINT You will now use this information to take a position on whether or not you feel that genetic modification should be pursued. Consider plants, animals, and humans specifically. Write your opinion in your interactive notebook.
