IB Biology D4.1.8 Modelling selection
Practise interpreting models of selection, including guppy colouration, predators and measured trait changes across generations.
How this is tested
- interpret data showing how predation influences visible male traits
- explain how controlled experiments model natural and sexual selection pressures
- describe trends in selected traits, such as decreasing size under predation
