Question

The principle that gives the geneticists a tool to determine when evolution is occurring is

• A. Chemiosmotic theory
• B. Hardy-Weinberg principle
• C. Malthusian principle
• D. Cloning theory

Answer 1

The correct option is B Hardy-Weinberg principle

• Hardy-Weinberg's principle gives the geneticists a tool to determine when evolution is occurring.
• Geneticists use this principle to calculate a starting point allele frequency and this frequency is then compared with the frequencies measured at some future point.
• The degree of evolutionary change is determined by calculating the difference between the observed frequencies and frequencies based on this principle.

Thus, the correct answer is option B.
