Welcome to Biology.SE Your question stems from the confusion between measuring a recombination rate and the actual recombination rate. In the A/A, B/B individuals you describe, recombinations still occur. Those recombination just don't affect linkage disequilibrium between the Aa and the Bb loci as there is no variance at those loci in the individuals you ...

There is at least one known case where both the DNA and RNA versions of the same aptamer sequence bind the same target (Lauhon and Szostak, 1995). But you can't generalize this, there are two differences in structure between RNA and DNA, the Uracil/Thymine change and the missing 2'-OH in DNA. Those differences can affect the binding and overall structure of ...
