The number of recombinant events for a number of meioses can be calculated from the maximum lod score and recombination fraction (theta).
number of meioses =
= (maximum lod score) / ((LOG10(2)) + ((1 - (maximum theta)) * (LOG10 (1 - (maximum theta)))) + ((maximum theta) * (LOG10 (maximum theta))))
number of recombinations =
= (number of meioses) * (maximum theta)
number of nonrecombinants =
= (number of meioses) - (number of recombinations) =
= (number of meioses) * (1 - (maximum theta))
