What is the relationship between recombination frequency and true genetic distance on a chromosome?
A)As genetic distance increases,the recombination frequency increases in a linear fashion.
B)As genetic distance increases,the recombination frequency increases,but never in a linear fashion.
C)As genetic distance increases,the recombination frequency first increases in a linear fashion,but then levels off to a frequency of 0.5.
D)As genetic distance increases,the recombination frequency first increases,but then decreases.

At short distances, the relationship between recombination frequency and true genetic distance is linear. However, as the distance between genes increases, the recombination frequency approaches 0.5 due to the phenomenon of crossover interference. Therefore, the recombination frequency increases at first but then levels off to a frequency of 0.5.
