Question

Given a population that contains genetic variation, what is the correct sequence of the following events under the influence of natural selection? 1. Well-adapted individuals leave more offspring than do poorly adapted individuals. 2. A change occurs in the environment. 3. Genetic frequencies within the population change. 4. Poorly adapted individuals have decreased survivorship. a. 2 → 4 → 1 → 3 b. 4 → 2 → 1 → 3 c. 4 → 2 → 3 → 1 d. 2 → 4 → 3 → 1

Answer 1

The correct option is (a) 2 → 4 → 1 → 3

A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.

What is genetic variation in population?

• The presence of various alleles, or different gene versions, within a population indicates genetic variety.
• If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
• Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.
