Figure 1.
A diagram of the UMC98 map of chromosome 1 showing markers that cross-hybridize between chromosome 1 and the other nine chromosomes. The vertical axis is the map position on chromosome 1. Black lines indicate markers mapped to chromosome 1, the standard chromosome; markers that cross-hybridize to other chromosomes are shown in gray with their map position(s) on the tester chromosome. Parentheses indicate the number of markers mapped to the same location.
