     This is data from a real experiment on hypertension in the mouse. 
     The phenotype is the blood pressure.  See the references below.
     Note that, for most markers, genotypes are available on only the
     individuals with extreme phenotypes.  At many markers, only
     recombinant individuals were typed.  We thank Bev Paigen and Gary
     Churchill for allowing us to distribute these data with the R/qtl
     package.

_F_o_r_m_a_t:

     The data is an object of class `cross'.  See `read.cross' for
     details. There are 250 backcross individuals typed at 174 markers
     (actually one contains only missing values), including 4 on the X
     chromosome, with one phenotype (blood pressure).
