Variation in SpeciesConceptual concept
Check understanding
- Gives examples of continuous and discontinuous variation in humans
- Distinguishes between genetic causes of variation (inherited differences) and environmental causes (diet, sunlight, etc.)
- Explains why sexual reproduction produces greater variation than asexual reproduction
- Draws or interprets a frequency graph showing continuous variation
“If your child looked around a classroom and noticed that everyone has slightly different heights, hair colours, and eye colours, could they explain why these differences exist — and which ones are inherited, which are down to the environment, and which are both?”
