Population genetic theory tells us that if D. is linkage disequilibrium at generation t and ris the probability of recombination between the two loci, then D = (1 - ) D. How does D. vary from generation to generation? O D, tends towards zero, faster if the recombination probability ris larger. D, tends towards zero, faster if the recombination probability ris smaller. O D, becomes larger and larger. D; stays constant.
