Thanks to this relationship, we can use the frequency of recombination events between two genes (i.e., their degree of genetic linkage) to estimate their relative distance apart on the chromosome.
A genetic map shows the map distance, in cM, that separates any two loci, and the position of these loci relative to all other mapped loci. The genetic map distance is roughly proportional to the physical distance, i.e., the amount of DNA between two loci.
To calculate the map distance between two genes, follow these steps: 1. Determine the recombination frequency: Obtain data on the number of recombinant and non-recombinant offspring of specific gene combinations through experimentation or literature research.
A genetic map indicates the relative distance between genes or markers, represented by the recombination value and measured in cM. A physical map highlights the physical distance between genes or markers, the distance unit is a length unit, such as micrometers (μm) or base pair numbers (bp or kp).
