What does genetic recombination do ?
Assuming Haldane 's map function , where the number of chromosomal crossovers is according to a Poisson distribution , a genetic distance of " d " centimorgans will lead to an odd number of chromosomal crossovers , and hence a detectable genetic recombination , with probability formula_1 formula_2 where " sinh (·) " is the hyperbolic sine function .
