Study Guide Linkage and Mapping After lectures on linkage, you should be able to: Answer the following questions from your textbook: o Chapter 7 o 4, 13, 14, 21, 24, 27, 28, 29, 30 Determine if genes are linked based on the different gametes formed. Define linkage and explain why linkage modifies independent assortment of two traits Distinguish between parental and recombinant phenotypes and calculate recombination distance (centiMorgans) Map a linear sequence of genes on a chromosome using given recombination frequencies from experimental data (Both 2 and 3 point crosses)
