Therefore, for any fixed volume of maternal plasma, the number of quantifiable sequences would be much greater than the number of DNA molecules that could serve as templates for detection by gene locus-specific assays. Hence, precise detection of the over- or underrepresentation of sequences from an aneuploid chromosome could be more readily achieved.
