Question 1:

What is genetic drift?

Explanation: Genetic drift refers to the change in allele frequencies in a population due to chance events. It is more pronounced in small populations, where random fluctuations can have a significant impact on allele frequencies over generations.

Question 2:

What is gene flow?

Explanation: Gene flow refers to the movement of individuals and the exchange of genetic material between populations. It can occur through migration, where individuals move from one population to another, and contribute their genetic diversity to the receiving population.

Question 3:

Which of the following is more likely to cause genetic drift?

Explanation: Genetic drift is more likely to occur in small population sizes. In larger populations, chance events have a lesser impact on allele frequencies, while in smaller populations, random fluctuations can lead to significant changes in allele frequencies over time.

Question 4:

Which of the following is more likely to cause gene flow?

Explanation: Gene flow is more likely to occur through migration between populations. When individuals move from one population to another, they bring their genetic material with them, introducing new alleles and increasing the genetic diversity of the receiving population.

Question 5:

Which of the following is an example of genetic drift?

Explanation: The random loss of a rare allele in a small population is an example of genetic drift. In small populations, chance events can lead to the disappearance of certain alleles over time, reducing the genetic diversity of the population.
