Discuss the relationship between genetic distance and physical distance between two linked genes
What will be an ideal response?
Distances on genetic maps are measured in map units (centimorgans) and on physical maps, distances are measured in base pairs.
The units of distance on a genetic map are expressed as a percentage of crossing over, where 1 map unit is equal to a 1% crossover frequency. Therefore, genetic maps only give an indication of the relative distance between two linked genes.
