Statistically, this is that the maximum mean recombination frequency is 50%. Recombination defined this way means that Gene A and Gene B from one chromosome are not 'together' on the same chromosome after recombination. That means that the recombination frequency is the probability of an odd number of recombination events …

WebFeb 3, 2024 · Dai and Kong (2024) analyzed common chromosomal breakpoint regions among 586 carriers of reciprocal translocations and found the breakpoints occurred more in GC-rich sequences, which was associated with a high frequency of recombination and B-Z transformation of chromosome conformation (Collins et al. 1996).
