Question

Which of the following will not affect the frequency of the gene in a large population?

• A. A) Environmental selective pressure
• B. B) selective immigration
• C. C) Random mating
• D. D) Non random mating

Answer 1

The correct option is A A) Environmental selective pressure

• Selective pressures drive natural selection.
• Some members of the population will not survive and reproduce and, thus, will not pass on their genes into the next generation. This change in the genetic makeup of a population is called evolution.
• Hence, Environmental selective pressure will not affect the frequency of the gene in a large population.
• So, the correct answer is 'Environmental selective pressure'.
