The genetic map: a list with each component containing the marker
positions (in cM) for a chromosome. Each component has class
A or X according to whether it is an autosome or the X
chromosome. The components are either vectors of marker positions or,
for a sex-specific map, 2-row matrices containing the female and male
marker locations. The map itself is given class map.
