Linkage · Botany

The strength of linkage between two genes is:

  1. Directly proportional to the distance between them
  2. Inversely proportional to the distance between them
  3. Independent of the distance between them
  4. Directly proportional to the size of the chromosome
Show answer and explanation

Correct answer: Inversely proportional to the distance between them

Tighter linkage occurs when genes are physically closer together because there is less probability of a crossover occurring in the small space between them. As distance increases, linkage strength decreases.
