Answer Key: A Detailed Analysis
To help you review and understand the Amoeba Sisters' video on genetic drift, here is a detailed answer key based on the key points covered in the video:
- Q: What is genetic drift?
A: Genetic drift is a random process that changes the frequency of alleles in a population over time. It is a stochastic process that can lead to significant changes in the genetic makeup of a population, especially in small populations.
- Q: How does genetic drift affect small populations?
A: Genetic drift has a more significant impact on small populations because the random sampling of alleles can lead to substantial changes in allele frequencies. This is due to the fact that a smaller number of individuals means that the random sampling of alleles has a greater impact on the overall genetic makeup of the population.
- Q: What is the founder effect?
A: The founder effect occurs when a new population is established by a small number of individuals from a larger population. This can lead to a different genetic makeup in the new population compared to the original population, as the founding individuals may not represent the full genetic diversity of the original population.
- Q: What is the bottleneck effect?
A: The bottleneck effect happens when a population undergoes a severe reduction in size, leading to a loss of genetic diversity. This can occur due to natural disasters, disease outbreaks, or other factors that significantly reduce the population size. The remaining individuals may not represent the full genetic diversity of the original population, leading to a loss of genetic variation.
