Answer:
Genetic drift
Explanation:
Genetic drifts is a change in the frequencies of alleles due to chance or at random. Therefore there is no environmental or survival influences.
There are two types. The founders effect caused when a small group migrates from a larger group and forms a new population causing a change in the genetic pool.
Bottleneck effect is caused by the sudden reduction of population due to environmental or human activities.
The observed genetic changes in the question were due to genetic drift.

Answer:the part of the brain that has most likely been damaged in this experiment is the suprachiasmatic nucleus (SCN) found in the hypothalamus of the brain.
Explanation:
circadian rhythms are behavioural changes that respond to light and darkness in an organisms environment. The sleep-inducing wake cycle is a good example of a circadian rhythm. In the experiment, the disruption of the mouse SCN led to development of imbalances in the circadian rhythm of sleep and wake cycle leading to falling asleep and waking up at random times of the day and night. I hope this helps. Thanks
