Final answer:
The recombination frequency that corresponds to independent assortment and the absence of linkage is 50%.
Step-by-step explanation:
Independent assortment refers to the random distribution of alleles on different chromosomes during meiosis. In this case, the recombination frequency would be 50% (c). This means that 50% of the offspring will have recombinant alleles and 50% will have parental types.
