Solution
Verified by Toppr

  • 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'.

Q5
Assertion: Hardy-Weinberg principle states that in the absence of disturbing influences, gene frequencies of large populations of sexually reproducing organisms do not change, provided that matings, occur at random.

Reason: The disturbing influences include mutation, gene flow, genetic drift, genetic recombination and natural selection.
