Q1.Natural selection can lead to _________. Choose the correct answer from the options given below:

  • (a) stabilisation
  • (b) genetic drift
  • (c) directional change
  • (d) disruption.
  • A(a) only
  • B(a), (c) and (d) onlyAnswer
  • C(a), (b), (c) and (d)
  • D(a) and (c) only

Explanation

Natural selection acts on a distribution of variation in three recognised ways: stabilising selection favours the mean, directional selection shifts it, and disruptive selection favours both extremes. Genetic drift is excluded because it is random change in allele frequency, not selection at all.

Q2.A population of diploid organisms is at Hardy-Weinberg equilibrium. If the frequency of allele A is 0.1, the frequency of AA is ________.

  • A0.01Answer
  • B0.02
  • C0.10
  • D0.99

Explanation

Under Hardy-Weinberg the genotype frequencies are p² + 2pq + q² = 1, where the homozygote AA has frequency p². With p = 0.1 that gives p² = 0.01. Reading 0.10 straight off the allele frequency is the trap.

Q3.Given below are two statements: In the light of the above statements, choose the most appropriate answer from the options given below:

  • Statement I: Modern Homo sapiens arose in Australia and moved across continents.
  • Statement II: Homo sapiens arose around 75000 to 10000 years ago.
  • ABoth Statement I and Statement II are correct
  • BBoth Statement I and Statement II are incorrect
  • CStatement I is correct but Statement II is incorrect
  • DStatement I is incorrect but Statement II is correctAnswer

Explanation

Statement I names the wrong continent — modern Homo sapiens arose in AFRICA and migrated outward, developing into distinct races. Statement II is right: that emergence is placed during the ice age, roughly 75,000 to 10,000 years ago.
