Fig. 2. Positioning of chromosome territories distributed radially in spermatozoa. Measurements were taken from the centre of a territory to the nearest edge. This measurement was normalized by dividing it by the length of the sperm. Data are plotted from the most peripheral chromosomes on the left-hand side to the most internal chromosomes on the right-hand side. (A) Duroc. (B) Landrace. (C) Large white.
