I think a Kosambi centimorgan is just a name for an ordinary centimorgan,
when that centimorgan is estimated from recombination fractions, using
the mapping function of Kosambi:
Kosambi, D. D. 1944. The estimation of map distance from recombination
values. Annals of Eugenics 12: 172-175.
There are other mapping functions, and there is no real reason to append the
name of the mapping function to the name "centimorgan" as if what it
calculates is incommensurable with ordinary centimorgans.
