4. Genetic Mapping and Linkage

In this chapter, we focused on linkage, chromosomal mapping, and many associated phenomena. In the process, we found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter, what answers would you propose to the following fundamental questions?When designed matings cannot be conducted in an organism (for example, in humans), how do we learn that genes are linked, and how do we map them?

In the process, we found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter, what answers would you propose to the following fundamental questions?How do we know that sister chromatids undergo recombination during mitosis?

From the explanations given in the chapter, what answers would you propose to the following fundamental questions?How do we know that crossing over results from a physical exchange between chromatids?

In the process, we found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter, what answers would you propose to the following fundamental questions?How do we know that specific genes are linked on a single chromosome, in contrast to being located on separate chromosomes?
