4.14 In the picture below the difference is shown between the genetic map (x-axis in cM) and the physical map (y-axis in Mb – Megabases). Can you calculate (estimate) the number of bases per cM for the first 50 cM, in the centromeric region and in the last 80 cM. How large is the region in cM and Mb where there is hardly any recombination? Many markers have been determined in this region but in the picture we see only one. It appears that there is only one marker because all identical segregating markers minus one have been removed from the data set.
