Imagine you are a scientist observing rats in the wild. As the rats reproduce, rats born with white fur slowly begin to outnumber rats with black fur. In three to five sentences, provide two or more different explanations of why the rats with white fur might be outnumbering the rats with black fur.(4 points)

One possible explanation is that the mutation that causes white fur is advantageous in the rats' environment, giving them a better chance of survival and reproductive success. Another explanation is that rats with white fur are more attractive to potential mates, leading to higher rates of breeding and passing on the white fur gene to their offspring. Additionally, it's possible that genetic drift is playing a role, with chance events leading to the increased frequency of the white fur gene in the rat population.

Pretend you are a scientist observing three different varieties of a single bird species that are part of the same population. In three to five sentences, describe what genetic variations exist in your population. Then, using reasoning skills and mock evidence from your observations, describe the impact these traits have on the birds’ relationships with their environment and predators.(4 points)

In my population of a single bird species, I have observed three different varieties. One variety has a longer beak, another has brighter feathers, and the third has larger wings. The genetic variation in the three varieties is likely due to differences in the genes responsible for these traits. The longer beak may help the birds to access food that is harder to reach, such as those on tree branches, while the brighter feathers may attract mates and ward off predators. The larger wings may allow the birds to fly faster and further, improving their chances of survival during migration and escape from predators. Ultimately, these genetic variations and the resulting traits play a significant role in the interactions between the birds and their environment and predators.

Genetic variations exist in my population of a single bird species, including longer beaks, brighter feathers, and larger wings. These traits impact the birds’ relationships with their environment and predators by allowing them to access difficult-to-reach food, attracting mates and warding off predators, and improving their chances of survival during migration and escape.

Compare and contrast the advantages and disadvantages of selective breeding versus genetic modification. Why might a person choose to use selective breeding over genetic modification? Why might a person choose to create a GMO over a selectively bred organism? Use three to five sentences to formulate your argument.
