Take the Test
In this lesson the students are presented with an intriguing dilemma about whether a man should have a screening test after his fiancée has found out she is a carrier of sickle cell disease. Students use information presented by experts to weigh up the options and come to a reasoned judgement. Students use knowledge about inheritance to interpret genetic diagrams, including family trees. They then make a decision by identifying issues that need to be considered in choosing to have a genetic test.
