A disorder that causes nearsightedness is caused by a genetic mutation. Nearsightedness was harmful to people living on a small island because they relied on sight to interpret their distant surroundings. In the 1600s, a huge storm killed many of the people on the island. Before the storm, 0.1% of the people had this disorder. Of the 50 people who survived the storm, 2% were nearsighted. Within a few generations, 10% of the islanders were nearsighted. Would a biologist agree or disagree with the following statement about the high rate of nearsightedness in the islanders after the storm?
a. The high rate was caused by new mutations that resulted in genetic
If we infer that the frequency of nearsighted individuals could be evidence for genetic drift, which of the following statements are true?
a. Nearsightedness must have become more common through natural.
b. Nearsightedness must have become more common through people.
c. Nearsightedness must have become more common through new
