If two genes on the same chromosome show a recombination frequency of 1%, they are approximately
Aon different chromosomes
Bcompletely unlinked
Ctightly linked, very close together
Dlocated on the Y chromosome only
Answer & Solution
Correct answer: C. tightly linked, very close together
Low recombination frequency means crossovers between the two loci are rare — the genes sit close to each other on the chromosome. Sturtevant's convention: 1% recombination = 1 map unit (centiMorgan).
