Question
Alchemase is an enzyme found in some geese that converts lead into gold.This is a restriction map of the goose alchemase gene:
The SalI restriction site in the box is polymorphic. Geese with a functional alchemase gene will lay golden eggs when fed a diet rich in lead. A functional alchemase gene (which is dominant to a mutation that inactivates the gene) has that SalI site. Most geese have a mutation that inactivates the alchemase gene, and that mutation also mutates the SalI site so that it no longer will be cut. These geese do not lay golden eggs, and will die if fed large amounts of lead. Someone tries to convince you to buy a goose that supposedly lays golden eggs, but you are skeptical and manage to get a DNA sample from the goose. After digesting the goose
