Imagine you are an evolutionary biologist studying two closely related species of butterflies in the same forest. Species A has a peak mating season in early spring, while Species B mates in late summer. Additionally, Species A uses a unique wing pattern to attract mates, which is not recognized by Species B. a. Identify and explain the types of pre-zygotic barriers that are likely preventing these two species from interbreeding (3 marks) b. Provide one possible scenario related to genetic drift that would further influence the genetic divergence between these two species over time. Use and describe the proper terminology as discussed in class (2 marks).

One strand of a DNA double helix has the base sequence TGCATGGAATCG. During replication, a point mutation occurs at the 5th base, changing it from T to C. a. Create the complimentary base sequence for the opposite strand of the mutated DNA double helix? b. Identify the point mutation that has occurred.
