• The standard unit of distance on a genetic chromosome linkage map is the Centimorgan (cM), named by J. B. S. Haldane in honor of geneticist Thomas Hunt Morgan.
• One centimorgan represents a recombination frequency of $1\%$ ($0.01$).
• nalysis:
• (Centimorgan): Correct.
• (Morgan): Represents $100\%$ recombination ($1\text{ Morgan} = 100\text{ cM}$).
• Options 3 & 4: Fictitious or pressure units.

Correct option: (1) Centimorgan
