Establish relative gene positions using two-point cross data.
Relative positions of genes are determined by gene mapping. A gene map represents a spatial sequence of genes present on a chromosome. Genes are present on specific locations called locus of a gene. These loci can be used as a molecular marker to estimate the distance between specific genes present on a chromosome.
