ABSTRACT

Genetic maps provide the linear orders of genes along the chromosomes and the distance among them, which is calculated based on the recombination frequencies. Genetic mapping allows determining the linkage relationship between genes and markers and provides the framework for the isolation of genes based on their positions on the map. The early maps were mostly based on the small linkage groups containing a limited number of the genes, which control the simple-inherited traits showing visible and discrete variations, such as color (Paran and Levin 2007). The development of molecular markers allowed the construction of saturated maps representing the entire chromosome set of the organism and in locating the genes controlling the quantitative traits that display continuous variations and often determined by multiple genes.
