A small population of horse-like animals have been relocated to an island. This new environment is different from their normal environment.
3
The island is colder and the only food source is a fruit that turns bright red when ripe and is located higher up in the trees. There are no predators on the island.
4
If we could travel hundreds of years into the future, what might we find on the island? Use your knowledge of natural selection to determine the following:
5
The animal has an allele for long hair and an allele for short hair. Which would most of the horse-like animals have and why?
6
The horse-like animal has an allele for brown eyes and an allele for blue eyes. Which one would they most likely have and why?
7
The horse-like animal has an allele for a long tail and an allele for a short tail. Which one would the animal have and why?
8
The horse-like animal has an allele for good hearing and an allele for poor hearing. Which one would they most likely have and why?
9
The horse-like animal has an allele for fast running and an allele for slow running. Which one would the animal most likely have and why?
10
The horse-like animal has an allele for color vision and an allele for no color vision. Which one would they most likely have and why?
11
The horse-like animal has an allele for a long nose and an allele for a short nose. Which one would they most likely have and why?
12
The horse-like animal has a gene for a long tongue and an allele for a short tongue. Which one would they most likely have and why?
