In pedprobr: Probability Computations on Pedigrees

Genetic map functions

Description

Simple implementations of the classical map functions of Haldane and Kosambi, relating the genetic distance and the recombination rate between two linked loci.

Usage

haldane(cM = NULL, rho = NULL)

kosambi(cM = NULL, rho = NULL)

Arguments

cM	A numeric vector with genetic distances in centiMorgan, or NULL.
rho	A numeric vector with recombination rates, or NULL.

Value

A numeric of the same length as the input.

Examples

cM = 0:200
dat = cbind(Haldane = haldane(cM = cM),
            Kosambi = kosambi(cM = cM))
matplot(cM, dat, ylab = "Recombination rate", type = "l")
legend("topleft", legend = colnames(dat), col = 1:2, lty = 1:2)


rho = seq(0, 0.49, length = 50)
dat2 = cbind(Haldane = haldane(rho = rho),
             Kosambi = kosambi(rho = rho))
matplot(rho, dat2, xlab = "Recombination rate", ylab = "cM", type = "l")
legend("topleft", legend = colnames(dat), col = 1:2, lty = 1:2)
