Optimal selection fraction

Description

Functions to find optimal selection fractions given cost.

Usage

optselection(cost,d=0,G=NULL,cross)
optselection.bc(cost,d=0,G=NULL)
optselection.f2(cost,d=0,G=NULL)

Arguments

cost	Cost per genotype in units of raising individual
d	Marker spacing in Morgans
G	Genome size in Morgans
cross	Cross type, "bc" or "f2"

Details
