Distribution of failures to exclude 128 individual hairs over the dates of testing based on date of DNA extraction of each hair. Day of the month on the top line; on some days more than one sample was extracted. Dark colors are failures to exclude known individuals (K1-K5, K8). Lighter colors are types occurring more than one time (T1-T9) that do not match known individuals. Number within the box is size of hair in millimeters rounded up to the closest millimeter. C = canine, S = singleton types, NR = no results. Color key on the right.
