Punnett Squares: Predicting Traits (Part 2).
🎯 Your mission
Master the concept. Use it tomorrow.
⚡ The twist
Living things break the rules of non-living things — find the rule they break.
Mind = Blown
🌳 Trees can talk to each other through underground fungus networks.
Make a hypothesis first
Predict: what will happen to the plant if you change the water?
What You'll Learn
Punnett squares are tools for predicting the probability of offspring inheriting particular traits. They show all possible combinations of alleles from two parents.
Key Words
- recessive
- mutation
- natural selection
Steps
Look at the vocabulary words and write a definition for each in your own words.
Survey your class for a genetic trait (attached vs. free earlobes, tongue rolling, hitchhiker's thumb). Create a bar graph of the results.
Draw a detailed diagram of what you observe.
Write a conclusion: what did your results show? Did they match your prediction?
