More (homework) Natural Selection Practice Problems 2023 - 2024

FYI - this is the homework. The first question is the same as the one we did in class, but the rest of the questions are different. 

This is a continuation of the work we did in class together. You can discuss this with your peers and me, but you should be writing your own answers.

When you click submit the "correct" answers will appear under your answers. The short answers will be "graded" as wrong, but that's just because you didn't write exactly what I wrote word for word (which makes sense!). This isn't graded on correctness but rather whether you complete it thoroughly. Use this as an opportunity to practice what you have learned thus far!

Don't forget to compare your answers once you submit!

Part 1:
Here are a bunch of examples of flowering plants in an environment and how the trait of color/being poisonous might change in frequency over time (these are all different scenarios - one doesn’t lead into the other). You should discuss be determining what you think might happen over time in each environment/scenario.

Things to note -
The flowering plants are eaten by rabbits. If there aren't rabbits in the area the plants aren't being eaten.
If a flower is white it is not poisonous. If a flower is red it is poisonous.
Assume the red poisonous flowers don't kill the rabbits, they just make them sick for a day
Being white and not poisonous/red and poisonous is a genetic trait that can be passed on and you need a random mutation for a new trait to arise
Assume the flowering plants won't be eaten to the point of extinction
Include the vocabulary from the beginning in your answers. FYI - my answers are 3-5 sentences long.

What do you think will happen in this scenario (i.e. what will happen to the frequency of white/red flowering plants over 10 years - remember frequency and population size are not the same thing). Why do you think this?

Part 2:

The following are examples of natural selection graphs. Identify the type of natural selection that is illustrated in the graph and make up a scenario that would fit that graph (you need to make sure you address the organism on the y-axis, the traits on the y-axis, environment, time, etc.) using vocabulary. FYI - My answers are about 7-8 sentences long.
