8. (4 pts) Construct a genetic map based on the following recombination data. Your map should show the position of each gene (use the map below and space genes roughly the appropriate distance from each other). LABEL DISTANCES BETWEEN INDIVIDUAL GENES. Genes % crossing over AB 1.5 AC 0.5 AD 2.6 BC 1.0 BD 4.1 CD 3.1 Genes % crossing over AB 1.5 AC 0.5 AD 2.6 BC 1.0 BD 4.1 CD 3.1.
