Next, you’ll build a simulation based on what you think will happen because of natural selection. Here are two considerations: Some individuals with harmful characteristics can still successfully reproduce, but they have an overall lower chance of doing so compared to organisms with neutral or beneficial traits. Natural selection may affect distribution of traits. It’s possible that harmful traits could eventually disappear from the gene pool. Don’t worry about precise population numbers. Based on your understanding of natural selection, you’ll be modeling only one scientifically plausible trend that can occur. There are several correct variations of this diagram. You’ll explain the justification for your choices in part E. Assume that these plants have a life expectancy of about one year, but the rate of reproduction keeps their population consistently around 2,500 organisms. Using the same elements you used in part C, draw simulations for year 5 and year 10. Clearly label each simulation.

In german cockroaches, curved wing (cv) is recessive to normal wing (cv+). bill, who is raising cockroaches in his dorm room, finds that the frequency of the gene for curved wings in his cockroach population is 0.6. in his friend joe’s apartment, the frequency of the gene for curved wings is 0.2. one day joe visits bill in his dorm room, and several cockroaches jump out of joe’s hair and join the population in bill’s room. bill estimates that, now, 10% of the cockroaches in his dorm room are individual roaches that jumped out of joe’s hair. what is the new frequency of curved wings among cockroaches in bill’s room? 0.69 0.4 0.5 0.31 0.20
