Ques. 1NEET 2016 (Phase 1)

Which of the following structures is homologous to the wing of a bird ?

  1. Wing of a Moth
  2. Dorsal fin of a Shark
  3. Flipper of Whale
  4. Hindlimb of Rabbit

Answer

(3) Flipper of Whale

Solution

The wing of a bird is a modified forelimb.

⇒ As per NCERT, the forelimbs of whales, bats, cheetah and human share similar anatomical structure (humerus, radius, ulna, carpals, metacarpals and phalanges) — they are homologous.

∴ The flipper of a whale (forelimb) is homologous to the wing of a bird.

∵ Wing of a moth is analogous, a shark's dorsal fin is not a limb, and a rabbit's hindlimb is not a forelimb.

According to Darwin, the organic evolution is due to -

  1. Reduced feeding efficiency in one species due to the presence of interfering species
  2. Competition within closely related species
  3. Intraspecific competition
  4. Interspecific competition
Ques. 9NEET 2013

The tendency of population to remain in genetic equilibrium may be disturbed by :

  1. lack of random mating
  2. random mating
  3. lack of migration
  4. lack of mutations
Ques. 10NEET 2013

Variation in gene frequencies within populations can occur by chance rather than by natural selection. This is referred to as :

  1. Genetic drift
  2. Genetic load
  3. Genetic flow
  4. Random mating
Ques. 11NEET 2013

The process by which organisms with different evolutionary history evolve similar phenotypic adaptations in response to a common environmental challenge is called :

  1. Convergent evolution
  2. Adaptive radiation
  3. Natural selection
  4. Non-random evolution
