Advances in Genetics NotesSelective 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)

Advances in Genetics NotesGenetic 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.

Advances in Genetics NotesCloning: 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.
