IB Biology A4.1.3 Evidence from selective breeding
Practise using crop, cattle and dog breeding examples to show how human selection produces heritable variation over time.
How this is tested
- distinguish selective breeding from natural selection in animal and crop examples
- apply breeding evidence to explain higher milk yield or varied dog phenotypes
- outline how choosing parents with desired traits changes populations over generations
