Question

If 15% of the gametes produced after meiosis are recombinant for two genes, the distance between the two genes will be

• A. 7.5 cM
• B. 30 cM
• C. 60 cM
• D. 15 cM

Answer 1

The correct option is D 15 cM

The physical distance between the genes is measured in map units or recombination units, centimorgan (cM) is the unit used for its measurements.
A centimorgan is a unit of genetic distance that represents 1% recombination during meiosis.
1% recombination = 1cM distance between the two genes
15% recombination = 15 cM
Therefore, 15 cM will be the distance between the genes.
