Summary Introduction

To explain:

How bottleneck effect and founder effect lead to genetic drift.

Introduction:

Genetic drift represents the change in the gene pool of a population occurred by chance. The changes in the gene pool occur due to mutation in the genetic material. The variations in the genetic material are the main cause of evolutionary changes occurring in a population. Variation helps a population to gain an advantage over other populations.

Blurred answer
Students have asked these similar questions
Relate the process of genetic drift to genetic bottlenecks and the founder effect, using examples.
What type of event could cause each type of genetic drift (founder effect and bottleneck effect)?
Differentiate genetic drift from genetic shift. What is genotype frequency? How do you get the genotype frequency? Give formula and cite example.
