If two genes A and B show 50% recombination frequency, it indicates that:
Show answer and explanation
Correct answer: The genes are either on different chromosomes or very far apart on the same chromosome.
A recombination frequency of 50% is the maximum possible value, indicating that the genes are assorting independently. This occurs when genes are on separate chromosomes or so distant on the same chromosome that crossing over is guaranteed.
