Relationships between the frequencies of aneuploid somatic and germinal cells. Top, Within-donor relationship between the frequencies of lymphocytes carrying sex-chromosome trisomy versus the frequency of sperm carrying sex-chromosome aneuploidyaneuploidy for ten donors (r²=0.665, P=.004). The intercept and the slope of the regression line are −0.3 (95% CI −1.3–0.7) and 1.5 (95% CI 0.6–2.3), respectively. Bottom, Within-donor relationship between the frequencies of lymphocytes carrying sex-chromosome trisomy and the frequency of XY sperm for ten donors (r²=0.697, P=.003). The intercept and the slope of the regression line are 0.3 (95% CI −0.4–1) and 1.9 (95% CI 0.9–3), respectively. All the data points fall well within the 95% CI for the regression lines. Frequencies are per 1,000 cells.
