Explain the experimental advantage of genetic mapping?
What is a molecular marker? Give two examples. Discuss why it isgenerally easier to locate and map molecular markers rather thanfunctional genes.
Traditional gene mapping has been applied successfully to a variety of organisms including yeast, fungi, maize, and Drosophila. However, human gene mapping has only recently shared a similar spotlight. What factors have delayed the application of traditional gene-mapping techniques in humans?
