Abstract
In the second part of their analysis of problems that arise in teaching and learning genetics at A-level, the authors take a detailed look at some published materials showing the widespread nature of the misuse of genetics terminology. It is not intended to aim criticism at any of the authors of the source materials examined—indeed the texts used were chosen for their obvious merit—but simply to indicate how widespread is the problem. It is the authors' contention that similar problems can be found in almost any text that attempts to address the study of genetics seriously. The paper concludes with some suggestions for improving the situation and a plea for urgent action.
