Question: What is the primary source of genetic variation in a population? (2022)

Options:

Mutation
Natural Selection
Gene Flow
Genetic Drift

Correct Answer: Mutation

Exam Year: 2022

Solution:

Mutation is the primary source of genetic variation in a population, as it introduces new alleles into the gene pool, which can then be acted upon by natural selection.

Questions & Step-by-Step Solutions

What is the primary source of genetic variation in a population? (2022)

Step 1: Understand what genetic variation means. It refers to the differences in DNA among individuals in a population.
Step 2: Learn about mutations. A mutation is a change in the DNA sequence that can create new traits.
Step 3: Recognize that mutations can introduce new alleles. Alleles are different versions of a gene.
Step 4: Know that these new alleles can change how individuals look or behave.
Step 5: Understand that natural selection can act on these new traits, helping some individuals survive and reproduce better than others.
Step 6: Conclude that mutations are the primary source of genetic variation because they create new alleles that contribute to diversity in a population.
