7 0

reduction in birds skeleton

Given a population that contains genetic variation, what is the correct sequence of the following events under the influence of
natali 33 [55]

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.

<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.
