Genetic engineering

Genetic Engineering


Selective breeding

Selective Breeding

  • Selective Breeding: allowing only animals with desired characteristics to produce the next generation.

  • Nearly all domestic animals and most crop plants have been produced by selective breeding.


Hybridization

Hybridization

  • Hybridization: crossing dissimilar individuals to bring together the best of both organisms.

  • E.g. Fuji apples: a cross of Red Delicious and old Virginia Ralls Genet


Inbreeding

Inbreeding

  • Inbreeding: the continued breeding of individuals with similar characteristics.

  • Risks of Inbreeding:

    • Small gene pool

    • Higher chance of genetic defects


Transgenic organisms

Transgenic Organisms

  • Transgenic: organisms contain genes from other species

  • A gene from one species can be inserted into cells of another and then be used to grow new organisms.


Types of transgenic organisms

Types of Transgenic Organisms

  • Transgenic Microorganisms

    • Bacteria used to proteins

  • Transgenic Animals

    • Study of diseases and production of proteins

  • Transgenic Plants

    • Disease resistant crops


Cloning

Cloning

  • Clone: a member of a population of genetically identical cells produced from a single cell.
