Inherited characteristics
Analyse and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms
What a learner can do afterwards
- Define inherited traits as characteristics passed from parents to offspring
- Collect or interpret data showing variation within a group (e.g. different heights, colours, sizes)
- Explain that while traits are inherited, there is natural variation among individuals of the same species
The lesson
You already know inherited traits pass from parents to their offspring. A puppy's fur color comes from its mom and dad. A sunflower grows into a sunflower because of its parent plant. But look closely at brothers, sisters, or plants from the same seed packet. They share inherited traits, yet no two look exactly the same.
Four kittens are born to the same mom and dad cat. All four inherited orange fur, so they all look orange. But one kitten is bigger than the others, and one has a small white patch on its paw. Same parents, same inherited trait, still some differences.
Variation is normal. It does not mean a trait failed to pass down. Living things from the same parents can still be different sizes, colors, or shapes.
Offspring inherit traits from their parents, but every individual still shows its own natural variation.
