Lec 18 - Crossing Over
... In fact genes are plotted on the chromosome on the basis of crossing over results between different pairs of linked genes. The actual distance between two genes is said to be equivalent to the percentage of crossing over between these genes. When the % of crossing over between two genes is 5, then t ...
