Consider the following scenario: A population of moderately pigmented snakes from Indiana migrate to northern Ohio. Several individuals from this population then make it out to some islands in Lake Erie. Eventually we start to see that snakes on the islands become lighter in color over time, whereas the snakes on the mainland become darker. Treating all the snakes as a single population in which all individuals were originally banded, graph how selection is affecting phenotype over time. For a few more points: Also indicate the relationship between fitness and phenotype as a result of the given mode of selection on a separate graph. Write down which mode of selection is operating and label all your axes PROPERLY.

Solution

Thanks for the question.

Some important points here are

1. since the nature alllowed these two snake into different geographical locations, because of the change in environmental condition and climatic conditions could have resulted in the change of color.

2. The dietery changes, the type and kind of food available may also have led to the change in the fitneess and skin color.

3. The food catching methods and processess, maybe different for the 2 types of populations and this could also have led to the changes in color and fitness.

4. the availability of additional necessary requirements such as availability of different types of water and extra nutrition in the form of substances available only in certain geographical locations may have resulted in changes in color and fitness.

The type of mode that may be active here is stabilizing selection as the trait in one location is favored more than the other.
