Bar chart of % U0–1–0–0 sequences per chromosome for a maternal plasma sample involving a female fetus (sample 1), a maternal plasma sample involving a male fetus (sample 2), and a mixture of plasma from two adult males (sample 3) processed using the new (protocol A) and original (protocol B) protocols. The percentage of genomic representation of each chromosome as expected for a repeat-masked reference haploid female genome was plotted as a reference (black bars).
