Question:

If the percentage of crossing over between two genes is \(10\), then the distance between two genes will be

Show Hint

Remember, \[ \boxed{ 1\% \text{ recombination} = 1\text{ cM} = 1\text{ map unit}. } \]

The Correct Option is B

Solution and Explanation

Step 1: Recall the relationship between recombination frequency and map distance. Genetic distance is measured in centimorgans (cM). \[ \boxed{ 1\% \text{ recombination } = 1 \text{ centimorgan}. } \]

Step 2:
Calculate the map distance. Given, \[ \text{Crossing over}=10\%. \] Hence, \[ \boxed{ 10\%=10\text{ cM}. } \] Therefore, \[ \boxed{10\text{ centimorgans}} \] is the correct answer. Thus, \[ \boxed{(B)} \] is the correct answer.
