The probability of selecting a locus for exchange, called the mixing

rate, can be very low or very high. A mixing rate of .5, for example,

means that any locus in the genome has a 50% chance of being selected

for exchange. The mixing rate acts like a variable rheostat, increasing or

decreasing the probability that the n-th locus on the genome in
