Law of homologous series was given by

  • A.Charles Darwin
  • B.Gregor Mendel
  • C.N. I. Vavilov
  • D.Swaminathan.

Answer: C

The law of homologous series was given by N. I. Vavilov.

The Russian botanist Nikolai Ivanovich Vavilov stated the law of homologous series in variation in 1920. It says that related species and genera show similar series of heritable variation, so a variant found in one species (for example, a grain colour or awnless form in wheat) can be expected in related species such as barley or rye. He is also known for the centres of origin of cultivated plants.

Darwin gave the theory of natural selection, Mendel the laws of inheritance, and M. S. Swaminathan led the Green Revolution in India; none of them proposed this law.
