Lesson details
Lesson outcome
I can explain how natural selection leads to advantageous genetic variants becoming more common over generations.
Show transcript
Some mutations cause genetic variants that cause advantageous adaptations in phenotype.
Individuals with these genetic variants are better adapted to compete, survive, reproduce and pass them on to offspring.
Natural selection causes advantageous genetic variants to become more common in the population over generations.
This causes advantageous adaptations in phenotype to become more common in the population over generations.
Examples explained at the genetic level using ideas about mutation, genetic variants and natural selection.
