A simulation of a BC1 cross of 150 organisms with a genome of around 500
cM consisting of 5 chromosomes. The format is that created by
make.analysis.objThis dataset is built up from several others. The basic data are:
{A vector of phenotype data}- little.bc.markers
{A map.frame of marker data} and
- little.dx
{A data frame with 50 rows and 2 columns that specify
