Worked practice questions

When every individual in a population carries an allele, that allele is said to be:

  1. Novel
  2. Fixed
  3. Lost
  4. Rare
Show answer and solution

Correct answer: B. Fixed

1. Selection can spread an allele fully. 2. It becomes fixed. 3. Deleterious dominant alleles may be eliminated. _Source: OpenStax Biology 2e, Chapter 19, The Evolution of Populations (CC BY 4.0)._

The sum of all the alleles in a population is its:

  1. Phenotype
  2. Karyotype
  3. Gene pool
  4. Genotype
Show answer and solution

Correct answer: C. Gene pool

1. Every allele of every individual counts. 2. That is the gene pool. 3. Selection and drift change it. _Source: OpenStax Biology 2e, Chapter 19, The Evolution of Populations (CC BY 4.0)._

Random change in allele frequencies with no advantage to the population is:

  1. Natural selection
  2. Gene flow event
  3. Point mutation
  4. Genetic drift
Show answer and solution

Correct answer: D. Genetic drift

1. It is simply the effect of chance. 2. That is genetic drift. 3. It often acts alongside selection. _Source: OpenStax Biology 2e, Chapter 19, The Evolution of Populations (CC BY 4.0)._
