alleryLinkage map distance of 1 cM (centimorgan) corresponds to:
A1% recombination frequency between two markers in offspring
BRandom
C1 chromosome
D1 mutation
Answer & Solution
Correct answer: A. 1% recombination frequency between two markers in offspring
1 cM = 1% recombination frequency.
**In human genome:** 1 cM ≈ 1 Mb on average (varies by location and sex).
Maximum linkage map distance = 50 cM (genes appear unlinked).
Used to construct genetic maps before physical sequencing.
