The Bivariate Fits tab is shown below:The Bivariate Fits tab contains the following elements:The maps plot Linkage Disequilibrium Units (LDU) on the y -axis and physical distance on the x -axis. The plots increase monotonically. Flat regions correspond to blocks with high LD, whereas jumps indicate places where LD is low; that is, breaks between blocks.The maps are created by fitting the Malecot model to sequential regions. Each parameter has a genetic interpretation. Refer to Maniatis et al . (2005) for additional details.
