The interpretation of normal and pathological variants of chromosome Y is discussed with reference to the literature and to personal cases. The effects on the phenotype of the increase or reduction in heterochromatin bound to chromosome Y are considered. The clinical pictures related to quantitative variations of the 'active' part of chromosome Y are described, and classification of so-called yp+ and double Y syndromes is then examined, these questions being of considerable importance in behavioural genetics.
