What is selective breeding?Show answer
Selective breeding (artificial selection) is the oldest form of genetic manipulation. Humans choose individuals with desirable traits and breed them together, so that over many generations those traits become more common. It has produced high-yield wheat, dairy cattle that give more milk, and merino sheep bred in Australia for fine wool.
What are transgenic organisms?Show answer
A transgenic (genetically modified) organism contains a gene transferred from another species, made using the gene technology techniques of restriction enzymes, ligase and vectors. Examples include bacteria engineered to produce human insulin, and crops modified for pest resistance or improved nutrition.
What is cloning?Show answer
Cloning produces genetically identical organisms or cells.
