Map distance is one of the key measures in genetics and indicates the expected number of crossovers between two loci. Map distance is estimated from the observed recombination frequency using mapping functions, the most widely used of those, Haldane and Kosambi, being developed at the time when ...
To help your users interpret a map, you can add multiple map legends, a color scale, and a distance scale. When you design a map, plan where you want the legends to display. You can specify the following information about each legend: Legend location. For example, legends can display ins...
