MS-LS4-5: Gather and synthesize information about technologies that have changed the way humans influence the inheritance of desired traits in organisms.
I can explain how people use technology to select traits in plants and animals.
Humans can choose traits they want in plants and animals.
Selective breeding has been used for thousands of years.
Modern technology allows scientists to influence inherited traits in new ways.
These technologies have both benefits and challenges.
People have selectively bred dogs for traits such as size, appearance, behavior, and abilities.
Farmers select animals with desirable traits to produce future generations with those characteristics.
Humans have selectively bred crops for traits such as larger fruits, better flavor, disease resistance, and higher yields.
Selective breeding and biotechnology can help scientists develop crops that can better meet the needs of a growing population.
