Genetic Drift

Q. Random genetic drift in a population probably result from :

1. Highly genetically variable individuals.
2. Interbreeding within this population.
3. Constant low mutation rate
4. Large population size.

Q. Genetic drift operates in :

1. Non reproductive population.
2. Slow reproductive population.
3. Small isolated population
4. Large isolated population

Q. Variation in gene frequencies within populations can occur by chance rather than by natural selection. This is referred to as :

1. Genetic flow
2. Genetic drift
3. Random mating
4. Genetic load

Q. Which of the following is the consequence of the founder effect?

1. Reduction of genetic variability in a new colony established by a small isolated group from a large population
2. A decrease in the genetic variability of a population due to a natural disaster
3. Both a and c
4. Changes in the genetic makeup of an individual
