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
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.
<h3>What is genetic variation in population?</h3>
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.

A food chain can usually sustain no more than six energy transfers before all the energy is used up. And so less energy is transferred at each level of the food chain so the biomass gets smaller.
