Figure 2. Comparison of genetic and physical distances for cloned markers on the classical genetic map of Arabidopsis.

Genetic distances are measured in cM. Physical distances are measured in estimated gene numbers (EGN) as explained in the text. Linear regressions were calculated for each arm of chromosomes 1, 3, and 5 and for both arms combined of chromosomes 2 and 4. Equations used to generate each regression line and to compare genetic and physical distances chromosome-wide are noted.
