Maximum recombination percentage is

A. 20

B. 30

C. 50

D. 60

Answer: Option C

Solution(By Examveda Team)

The maximum recombination percentage is 50.
The recombination frequency between two genes cannot be greater than 50% because a random assortment of genes generates 50% recombination (non-linked genes produce 1 : 1 parental to non-parental. Thus, the recombination frequency would be non-parental/total → $$\frac{1}{{1 + 1}} = 50\% $$  ).
