Which of the following represents a random change in allele frequencie

1.	Which of the following represents a random change in allele frequencies over the generation?(a) Bottleneck effect(b) Sewall Wright effect(c) Hardy-Weinberg effect(d) Ernst Mayr effect
Answer» Answer is : (b) Sewall Wright effect Genetic drift is also called as Sewall Wright effect. Also known as allelic drift. Genetic drift is the change in the frequency of an existing gene variant (allele) in a population. The evolutionary biologist Ernst Mayr proposed biological species concept. Hardy-Weinberg law is the fundamental law of population genetics. The attractions and loss of genetic variability has been termed as bottle neck effect.
