Question

Which of the following factors can change allelic frequency?
A. Gene flow
B. Natural selection
C. Random mating
D. Founder effect
E. Genetic recombination

• A. A, B, C, D, E
• B. A, B, E
• C. C, D, E
• D. A, B, D, E

Answer 1

The correct option is D A, B, D, E

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including mutations, natural selection, nonrandom mating, genetic drift, and gene flow.
A, B, D, E are all factors which can effect allele frequency. These cause exceptions to the Hardy Weinberg principle.
Random mating helps maintain allele frequency. Non random mating causes change in allelic frequency.
