The recombination frequency between two genes on the same chromosome can never exceed

  • A. 25 per cent
  • B. 40 per cent
  • C. 50 per cent
  • D. 100 per cent

Explanation

Once genes are far enough apart that a crossover happens between them in every meiosis, half the gametes are recombinant, the same figure as independent assortment. Frequencies above 50 per cent are therefore impossible to observe.
