    a. Compare traditional breeding and Marker Assisted Selection

    Genetic Map: Map representing the genes or QTLs (quantitative trait loci) markers on the genomes and the distance is measured based on centimorgan differences.
    Physical Map: A map representing the linkage groups, etc. of a genome and is expressed in terms of base-pair unit, which could be done by the presence/absence of markers based on the trait observation.
