(centiMorgans).

A recombination fraction between two markers, i.e., a number between
|
Haldane mapping function is defined as
dM = -(1/2) ln(1-2r),
for 0 ≤q r ≤q 0.5, where r
stands for the recombination fraction
in rcmb
. Kosambi mapping function is
dM = (1/4) ln [(1+2r)/(1-2r),
for 0 ≤q r ≤q 0.5, where
r
is defined as above.
Both functions return a number with a distance measured in cM
.
