During this investigation students will use two labeled game markers as a model for a monohybrid cross.
Mendel made his discoveries by crossing pea plants and keeping careful records of the outcomes of his crosses. Students can make similar observations using coins as a model. During this investigation students will use two labeled game markers as a model for a monohybrid cross.
Students should understand Mendels classic pea experiment.
1. Students participate and collect data .25 pts
2. Students correctly answer questions .25 pts
1-3. Answers will vary on these three questions.3. Students write thoughtful conclusion 5 pts
4. The series of 1000 tosses should most closely resemble the expected values (1:2:1), where the series of 10 tosses may not even be close.
5. The larger the number of trials, the closer the results approach expected ratios. Also, previous events do not affect future outcomes.
6. The results of genetics crosses follow the rules of probability (stated as the answer for #5).
