Scientists studied the 3,300-year-old mummy of King Tut, conducting DNA testing and CT scans. DNA tests were also performed on 15 other mummies, some of which belonged to relatives of the young king. Results confirmed that he was not a healthy man. Scientists found that the ruler suffered from a painful illness called Kohler disease. As a result, a severe lack of blood flow slowly damaged the bones of his left foot. These findings explain the 130 walking sticks and canes that were discovered in Tut's tomb.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.

In sheep, the allele for belly fur (a) is dominant to the allele for no belly fur (a). a mother with the genotype aa and a father with the genotype aa produce an offspring.
