2. Advances in Genetics Notes Selective Breeding : select or choose organisms with desired traits (features). Two techniques are: Inbreeding: mating (crossing) similar individuals having similar features. Hybridization: mating different individuals to produce offspring with the desired traits. Example: Corn (many kernels) X Corn (disease resistant) = Corn (many kernels + disease resistant)

3. Advances in Genetics Notes Genetic Engineering: genes from one organism are transferred into the DNA of another organism ( human to bacteria ). Purpose: produce new medicines, improve food crops, superplants, superhumans? ( future mankind ). Example: Bacteria plasmid (DNA ring) used to produce insulin for diabetics. Example: Bacteria plasmid (DNA ring) used to produce human growth hormone to help the development of very short people. Example: A firefly’s bioluminescence gene transferred into a cat’s egg can produce a cat that glows in the dark.

4. Advances in Genetics Notes Cloning: offspring (children) with the same genes as parent. That is, asexual (mitotic) reproduction artificially occurring in sexually reproducing organisms. Clone: Parent = Child ( genetically ) Identical Twins: Child A = Child B ( genetically ) Example clone: Dolly the sheep; parent and child are identical in appearance.
