I find it interesting how you were able to refute the null hypothesis in Part A of this lab since I also noticed how the size difference between the white and speckled beans can alter the results, but the Chi-square value from my group did not go over the critical value of 5.99. As for Part B, even though it did not work as planned according to your results and conclusion, I like how your group creatively decided to use spoons to pick the beans up. I also find it very satisfying that the graph and Chi-square value for both populations were similar. Although the spoons did not work to improve random selection, I think it did a great job in keeping the results between the two populations consistent and reliable. This would be a great simulation method for natural selection.
First off, I really like how this blog post is started by a paragraph briefly explaining the experiment, which gave a great sense for readers what is going on! I also think the punnett square gives a very clear visual to show where did you guys come up with the expected ratio, which is great for being clear. For the results from part B, it is surprising to see population A had such an extreme result where the 10th generation only have pinto beans left. Another remarkable thing did by your group is to use spoon instead of bare hands to pick up the beans, my group used bare hands and did not have very "random" data. However, using spoon to pick up the beans might be one of the reasons why there is that extreme result for population A. Overall, I think this blog post is very informative and clear, well done!
I liked that you described the procedure for each part of the lab. When the reader is going through your post, they can see the differences between what you did and what they did. For example, you guys used the spoon, which might be the reason for your results. My group tried to be as random as possible, so we use tweezers. For part one, I thought all groups were going to have similar results to the expected percentages, so it was interesting to see that you rejected your null hypothesis.
It's really interesting to see the black, red, and white beans slowly "die off" and be completely overrun by the speckled/pinto beans. I really like the how this post was organized its very colorful and easy to read!
I've had something similar happen in my group. Our red beads continuously grew in number as each generation passed, but our black beads completely died out towards the end. We tried to keep it as random as possible by just closing our eyes and scoop the beans out of a cup. I really like how you are self reflecting on your techniques and how that could have an effect on your entire experiment. It is definitely hard not to be biased when using our hands since you could feel that the pinto beans were bigger than some of the other ones. I liked how you talked about correcting the situation at hand.
