They exist both in regions influenced by industrial pollution and in others which are essentially unpolluted.

The haemoglobinopathies remain a valuable tool for the study of gene action in Man but in the last few years the emphasis in this field has changed from population genetics to the study of abnormal haemoglobin synthesis at a molecular level. This trend is particularly noticeable in recent work on thalassaemia.
