calc_Lstar {simcross}

Calculate adjusted chromosome length for obligate chiasma

Description

Calculate the reduced chromosome length that will give the target expected number of chiasmata when conditioning on there being at least one chiasma on the four-strand bundle.

Usage

calc_Lstar(L, m = 0, p = 0)

Arguments

L

Length of chromosome (in cM); must be > 50

m

Interference parameter for chi-square model

p

Proportion of chiasmata coming from no-interference process

Value

Adjusted length of chromosome
