Artificial Selection- Animal Pharm
For thousands of years, humans have used selective breeding techniques to breed domestic animals and plants. We have selected which parents will mate together based on their possession of particular features, to increase the chances that their offspring will have features that will suit our needs. This type of selective breeding is called artificial selection.
This program explores how science is changing the food that we eat. From double-muscled bulls to featherless chickens, this is breeding on a whole new level. Stepping into the world of transgenics, we encounter rabbits with a jellyfish gene in their DNA (they glow in the dark) and salmon engineered to grow four times faster than normal. We meet the all-new Enviropigs, which carry a man-made gene that makes their manure environmentally friendly, and check out genetically modified ’golden rice’, which, according to its creators, could save millions of lives in the developing world. Next we enter the world of cloning, where endless copies of an organism can be made, like a biological photocopier. We witness the astonishing process of cloning in action, and meet Charmayne James, the $1million cowgirl, who’s just cloned her legendary racehorse, Scamper.
Make sure you download and print the worksheet below, and answer the questions as you go. Take some time to consider your response to the final question as this may form the thesis of your next summative task- a persuasive piece about a genetic engineering topic of your choice.
